Download Time Calculator

The ultimate download time calculator is used to estimate how long it will take to download any file based on your download speed. Besides we can precisely calculate the download time for every file size, we also have a download simulator so you can see how download works based on the submitted data.

* This is only a donwload time simulation of how much time it would take to download the file.

How to use the Download Time Calculator?

It’s so easy it takes only 3 easy steps as follows.

  1. First, enter your internet connection speed. If you don’t know your transfer speed, click on the “Test my internet speed” sign and we will test it in a few seconds.
  2. Enter the file size of the thing you want to download. Don’t forget to choose the appropriate unit (e.g. KB, MB, GB, or TB).
  3. Click on the Calculate button to see the download time minimum required to download the file. You can also see a simulation.

How precise is the Download Time Calculator?

Your actual download speed depends on many factors so the download speed shown by the Download Time Calculator is theoretical. If you want to get the most accurate download time values possible, you should test your internet speed first.

What’s the difference between Mbps and MBps?

Mbps (or Mb/s or Mbit/s) stands for megabits per seconds. MBps (or MB/s) stand for megabytes for seconds.[1]

The formula to convert from Megabits per second to Megabytes per second:

  • Megabytes per second = Megabits per second ÷ 8

The formula to convert from Megabytes per second to Megabits per second:

  • Megabits per second = Megabytes per second * 8

Internet service providers always use the Mbps for communication the internet speed because it’s a larger number. So a 10 Mbps connection means 1.25 MBps.

Here are all the frequently used download speed data units:
