Data transfer speed is the amount of data transferred in a given time, for example when you download a file from the internet. When downloading a file, you will see a progress bar and download speed (eg in KB per second).
One way to calculate the data transfer rate is to calculate the amount of data transferred and the time it takes to download the data, with the formula; "Data transferred" divided by "transfer time".
Note: You can count data transferred in various sizes, such as KB, MB, GB, TB, and others. Transfer time can also be calculated in units of milliseconds, seconds, minutes, hours, and so on.
In this example, you have transferred 25 MB of data in 2 minutes.
Step
Step 1. To get speed in KB/sec, first convert MB to KB
Since 1 MB is approximately equal to 1000 KB, multiply 25 by 1000 to get 25,000 KB.
Step 2. Convert minutes to seconds
One minute is 60 seconds, and two minutes is 120 seconds.(2x60=120).
Step 3. Divide the number of KB by seconds to get the transfer rate (25,000 / 120 = 208.3)
Then, round up. After rounding up, the data transfer rate obtained is 210 KB per second.
