Download 600 MB
This download time calculator will help you determine the time it will take to download a file at a given internet bandwidth. An internet bandwidth provides information about a network's upload and download speed, and the faster the internet download speed is, the faster we obtain the file or the data we need. Keep on reading to learn how long it takes to download, let's say, your favorite video clip.

Nowadays, we can also transfer data wirelessly through radio frequencies like Bluetooth or Wi-Fi. We can now also upload or transfer data to the internet so that other people can access it. The internet is a series of computer networks running all across the world. With the internet, we can now easily send any file to our loved ones, even if they are a thousand miles away from us, as long as they also have access to the internet. All we need to do is upload our file to the internet. Then, to access our file, people have to download it to their devices.
Uploading and downloading data can take a while, depending on the file's size and transfer rate. Think of it like pouring water into a beaker. Pouring water from one beaker to another will only take a little amount of time. However, if we place a funnel on one beaker, the amount of water flow will decrease due to the narrow part of the funnel.
To better understand this, let us consider an example. Let's say that your friend wants to send you his new 400 MB (megabytes) video creation over his 10 Mbps (megabits per second) internet connection. On the other hand, you will be receiving the video file over your 5 Mbps home internet connection. For this example, let us assume that the upload and download speeds for both connections can use their entire bandwidths. Since the file will also be coming through the much lower 5 Mbps connection, this will be the maximum transfer speed that we can get for this data transfer. But, to determine the upload and download speeds of your connection, you can use any third-party speed test applications that can be accessed online through your browser.
Now that we know how to determine the transfer speed for our uploads and downloads, we can now calculate a file's download time or duration. Calculating download time is as simple as dividing the size of the file you wish to transfer by the transfer speed of the network that the transfer will go through. However, we have to be careful with the units we use since this could be quite confusing.
As shown above, the 400 MB video file will finish downloading in less than 11 minutes over a stable 5 Mbps connection. However, if somebody else in the house uses the internet while you're downloading this video file, it could take much longer to complete the download because of congestion in the data transfer. You may check the amount of data required with our video file size calculator.
Aside from calculating the download time of a file from the internet, you can also use this calculator to determine the transfer duration from, let's say, a computer to an external storage device like a USB flash drive. However, you must first know the transfer rate of your connection to calculate the transfer duration. You can also use this download time calculator to determine your download speed. However, for this, you have to time how long to download a particular file. Then, by entering the file size and the download time in our calculator, you'll be able to calculate your internet's download speed.
If you want to determine the actual time your download will take to complete, you can input the estimated download time into our time duration calculator. Our time duration calculator will help you determine the actual completion time of the download.
Like any Internet service, fiber optic Internet download speeds depend on your connection. Not all fiber services are created equal, much like broadband. Fiber is not distance sensitive like copper based services, but speeds can vary. However, there's no doubt that;
In the USA, fiber internet service is available to businesses just about everywhere. Fiber internet for residential users is more limited, but growing. At speeds up to 1 Gigabit per second, fiber internet delivers much faster downloads than broadband. As an example, if your broadband download speed is 50Mbps, (average U.S download speeds in 2020 were 54.99 Mbps), downloading a game, 100 songs, a full HD quality movie or 100 photos is up to 20 times faster with a Gigabit fiber connection.
Using common file types and sizes from the Apple.com site, the below table indicates how fast fiber internet service is. Check approximate download times for movies, songs, videos, TV shows and audio books, compared to common broadband speeds. Note: download speeds vary depending on your specific internet service connection. This can be due to common factors including line quality, your modem or hardware and the bandwidth your ISP uses to keep your Internet line 'open'.
Using fiber optic cables, which bundle glass strands to transmit data, a fiber optic internet connection offers high speed upload and download times. Fiber internet speed does not degrade over longer distances, like copper based internet connections. Additionally, a fiber connection allows for greater data capacity while limiting loss and interference. As it becomes more available and to satisfy user demands, fiber optic internet is becoming the main source of competition for broadband, DSL, cable, and satellite internet services
Fiber optic internet is currently the fastest, most-reliable internet service available. Fiber increases download and upload speeds and offers users faster access to various media types and larger file sizes. When it comes to business communications, fiber optic internet can increase productivity while reducing latency. Typically, fiber service offers unlimited data usage, faster cloud access, high speed symmetric connectivity, and unparalleled scalability. For those reasons, fiber optic internet is often a better solution, when it is available.
For many gamers, internet speed and bandwidth is essential for productive gaming sessions. Because fiber optic internet provides lower latency and is capable of downloading games and movies at a faster rate when compared to other internet connections, many support fiber as the ideal solution for both gaming and HD video streaming.
How long does it take to download or transfer a set large images, your video files, or your corporate data backup files? This calculator will chart the data transfer time, based on the size of your files, for a variety ofdifferent connection type . This calculator takes into account a default 10% TCP/IP network overhead. To use this speed calculator, simply type in your file size the box below.
A simple calculator with which you can calculate download time for a file depending on download speed. How long time it will take depends on file size, your own download speed and the server's upload speed. In these calculations it is assumed that your download speed is the bottleneck.
Input the file size and click on "Calculate". Then you will see the result for the different connection types to the right. You can also enter your own download speed in case the predefined download speeds doesn't match yours.
Downloading meteorological data can be a pain. Servers are under-powered,connections are slow and the "bean counters" figure that 800 GB will storea trillion spreadsheets so who would want more disk space? Can't help withthe last problem but downloading data in GRIB files can be madefaster.
Often people only need a few fields from a GRIB file. Forexample, the GFS forecasts contain over 600 fields per forecast time.Many people are only interested in a few fields such asthe precipitation or 500 mb heights. Assuming we only wantedtwo fields, downloading 600+ fields to get two fields is just silly.
Some datasets have pre-configured scripts to download the data.See Part 2 for more information.DetailsThe http protocol allows "random access" reading;however, that means that we need an index file and a httpprogram that supports random access. For the index file, wecan modify a wgrib2 inventory. For the random-access http(s) program, wecan use cURL. Both are freelyavailable, widely used, work on many platforms and are easilyscripted/automated/put into a cronjob.
get_inv.pl INV_URL grep (options) FIELDS get_grib.pl GRIB_URL OUTPUT     INV_URL is the URL of a wgrib/wgrib2 inventory       ex.      grep (options) FIELDS selects the desired fields (wgrib compatible)       ex. grep -F ":HGT:500 mb:" selects ":HGT:500 mb"       ex. grep -E ":(HGTTMP):500 mb:" selects ":HGT:500 mb:" and ":TMP:500 mb:"      GRIB_URL is the URL of the grib file       ex.      OUTPUT is the name of the for the downloaded grib file
The "get_inv.pl INV_URL" downloads the wgrib inventory off the net and addsa range field. The "grep FIELDS" uses the grep command to select desiredfields from the inventory. Use of the "grep FIELDS" is similar to theprocedure used when using wgrib/wgrib2 to extract fields. The "get_grib.plGRIB_URL OUTPUT" uses the filtered inventory to select the fieldsfrom GRIB_URL to download. The selected fields are saved in OUTPUT.Examplesget_inv.pl \ grep ":HGT:500 mb:" \ get_grib.pl out.grb  The above example can be written on one line without the back slashes. (Back slashesare the unix convention indicating the line is continued on the next line.) Theexample downloads the the 500 mb height from the 12 hour (f12) from the 00Z (t00z)GFS fcst from the NCEP NOMAD2 server.     get_inv.pl \ egrep "(:HGT:500 mb::TMP:1000 mb:)" \ get_grib.pl out.grb  The above example is similar to the earlier example except it downloads both the500 mb height and the 1000 mb temperature.Warning: Metacharacters In the beginning, you could filter the inventory with strings like egrep ":(UGRDVGRDTMPHGT):(1000500200) mb:" egrep "(:UGRD:200 mb::TMP:2 m above ground:)"First egrep was deprecated and was replaced by "grep -E". No big deal.Then someone decided to put egrep wildcards into the official level information.Imagine trying to do grep -E "(:UGRD:200 mb::HGT:PV=2e-06 (Km^2/kg/s) surface:)"You see the problem. The HGT level field contains "(" and ")".To get rid of the special meaning of "(" and ")", they shouldbe quote by \( and \). The caret "^" also has a special meaningand should be quoted too. The fixed line is grep -E "(:UGRD:200 mb::HGT:PV=2e-06 \(Km\^2/kg/s\) surface:)"You should backquote all the regex metacharacters including \,^,$,.,,?,*,+,(,),[,],,Sample Script Here is an example of downloading a year of R2 data.#!/bin/sh# simple script to download 4x daily V winds at 10mb# from the R2 archiveset -xdate=197901enddate=197912while [ $date -le $enddate ]do url=" -2/6hr/pgb/pgb.$date" get_inv.pl "$url.inv" grep ":VGRD:" grep ":10 mb" \ get_grib.pl "$url" pgb.$date date=$(($date + 1)) if [ $(($date % 100)) -eq 13 ] ; then date=$(($date - 12 + 100)); fidoneRequirements perl grep cURL grib files and their wgrib inventory on an http server get_inv.pl get_grib.plConfiguration (UNIX/Linux)The first two lines of get_inv.pl and get_grib.pl need to be modified.The first line should point to your perl interpreter. Thesecond line needs to point to the location of curl if it is noton your path.Usage: WindowsThere have been some reports that the perl scripts didn't work on Windows machines.The problem was solved by Alexander Ryan.Hi Wesley,thought this might be of some use to your win32 users. I had the following problem when running the get_grib.pl file as per your instructions. run thisgrep ":UGRD:" and I would get the error No download! No matching grib fields. on further investigation I found that it was just skipping the while STDIN part of the code. a few google searches later and I found that for some strange reason in the pipe I needed to specify the path or command for perl even though the file associations for .pl are set up. (don't fiqure) this works for me grep ":UGRD:" Regards and thanks for the fine serviceAlexander RyanAnother email from AlexanderHi Wesley,Further to my last email here are some details regarding the enviorment I run this all on for your referance. My computer is P4 1.7GHz with 1Gb Ram running Windows 2000 service pack 4Perl version :V5.6.1 provided by cUrl Version: 7.15.4 from grep & egrep: win32 versions of grep and egrep, I found both at provide some useful ports of common GNU utilities to native Win32. (no cygwin required) so far this is working fineRegards Alexander Apparently,    get_inv.pl INV_URL grep FIELDS perl get_grib.pl URL OUTPUT should work. Linux users probably will gravitate towards the cygwin system because itincludes bash, an X-server, compilers and the usual unix tools.TipsIf you want to download multiple fields, for example, precipitation and 2 meter temperature, youcan type,       URL=" "     get_inv.pl $URL.idx egrep ':(PRATETMP:2 m above gnd):' get_grib.pl $URL out The above code will put the precipiation and 2-m temp in the file out. Of course, egrep understands regular expressions which is a very powerful feature.If you are doing multiple downloads from the same file, you can save time by keeping a local copy of the inventory. For example,      URL=" "     get_inv.pl $URL.idx > my_inv     grep ":UGRD:"      grep ":VGRD:"      grep ":TMP:"  The above code saves two extra downloads of the inventory. Some people have slow internet connections. A user was complaining about baddownloads. Turns out that the user was using a modem and cURLwas "timing out". The user solved the problem by adding the following options to the cURL command "-y 30 -Y 30" which are found within get_inv.pl and get_grib.pl.The options tell curl to only "time out" when the download rate is less than 30 bytesper second for 30 seconds. Glad I don't have to use a modem.Notes for Data ProvidersThe grib data needs to accessable be on an http server. Often this is aminor change in the httpd configuration. 041b061a72
