Question

How do I calculate the time taken to transfer the files?

Community Answer

Say a file of 640,000 bits transfers by the rate of, say, 64 kbps, the time taken is 640000 / (64 x 1000) = 10 seconds.

Question

How do I calculate data transfer rates?

Community Answer

For example, 50 Mbps or “50 meg a second” is not 50 Megabytes per second, but rather 50 Megabits per second. So in order to calculate the transfer rate of a file size we need to convert the size to bits, however, you can't just say that 2 Gb x 8 will give you the number of bits in the file.

Question

How do I calculate the data transfer rate given size and baud rate?

Community Answer

2 kbytes = 2048 bytes. Transmission of a byte requires: 1 start bit; 8 bits = actual byte; 1 bit parity; and 2 bits stop for a total of 12 bits. The baud is 2048 * 12 = 24576 baud.

Question

How do I tell what my data transfer rate is in bytes?

Community Answer

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."

Question

What formula should I use to calculate how long it will take to transfer a 1GB file onto a USB 3.0?

Community Answer

You are given A by it stating "1GB" and S because the 1Gb is being transferred onto a USB3.0. Therefore, you should be able to use T = A/S. Don't forget to change 1GB into GB before you do the division.
