# How to Calculate Data Transfer Rate

Data transfer rate is the rate that a certain amount of data is transferred over a given period in time. An example would be when you download something online. While downloading you see the progress bar and the Data Transfer rate (e.i. Kilobytes per second KB/s).

One way this can be done is by a simple equation using how much data has been transferred and how long it took in total to transfer that data. The equation is: "DATA TRANSFERRED" divided by "TIME TAKEN"

EXAMPLE: You transfer 25 Mega Bytes (MB) of data in 2 minutes.

Since a Mega byte is roughly 1000 Kilobytes we will multiply it by 1000. We get 25,000 Kilobytes.

Since a minute is 60 seconds we know that 2 minutes is 120 seconds (2x60=120).

25,000/120=208.3. We'll round it too 210.

So now we have a rate of 210 KB/s.

One way this can be done is by a simple equation using how much data has been transferred and how long it took in total to transfer that data. The equation is: "DATA TRANSFERRED" divided by "TIME TAKEN"

**NOTE: DATA TRANSFERRED may be in the form of a variety of measurement e.i. KB, MB,GB,TB etc... AS well as that, the same applies to the TIME TAKEN e.i. milli-seconds, seconds, minutes, hours etc...**EXAMPLE: You transfer 25 Mega Bytes (MB) of data in 2 minutes.

**Steps****1. To get KB/s you must first convert Mega Bytes to Kilo Bytes.**Since a Mega byte is roughly 1000 Kilobytes we will multiply it by 1000. We get 25,000 Kilobytes.

**2. Convert minutes into seconds.**Since a minute is 60 seconds we know that 2 minutes is 120 seconds (2x60=120).

**3. Divide Kilo Bytes by Seconds to get the rate.**25,000/120=208.3. We'll round it too 210.

So now we have a rate of 210 KB/s.
