Enter the file size in megabytes and the upload time in seconds into the calculator to determine the upload speed in megabits per second (Mbps). This calculator helps you understand how fast your internet connection can upload a file.

Upload Speed Formula

The following formula is used to calculate the upload speed:

US = (FS * 8) / UT

Variables:

  • US is the upload speed (Mbps)
  • FS is the file size (megabytes)
  • UT is the upload time (seconds)

To calculate the upload speed, multiply the file size by 8 to convert megabytes to megabits, then divide by the upload time in seconds.

What is Upload Speed?

Upload speed is a measure of how quickly data can be sent from your device to the internet. It is an important aspect of internet connectivity, especially for activities that involve sending large amounts of data, such as video conferencing, online gaming, and uploading files to cloud storage. The speed is typically measured in megabits per second (Mbps).

How to Calculate Upload Speed?

The following steps outline how to calculate the Upload Speed.


  1. First, determine the file size (FS) in megabytes.
  2. Next, determine the upload time (UT) in seconds.
  3. Use the formula from above = US = (FS * 8) / UT.
  4. Finally, calculate the Upload Speed (US) in Mbps.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

File Size (FS) = 500 megabytes

Upload Time (UT) = 100 seconds
