undefined
Transfer-rate pages keep bits and bytes separate. One byte is eight bits, so Mbps and MB/s are not interchangeable.
For file-transfer estimates, round after converting between bits and bytes, then account for network overhead separately.
How to convert Mbps to KB/s
- Type the Mbps value in the calculator.
- Keep Mbps selected as the from unit and KB/s selected as the to unit.
- Use the instant result, or copy it with the copy button.
