What's the difference between KB and KiB?

KB (kilobyte) = 1000 bytes (SI/decimal). KiB (kibibyte) = 1024 bytes (binary/IEC). Operating systems and storage devices use different standards.

What does the transfer time show?

Enter a network speed in Mbps and the tool calculates how long it would take to transfer the specified amount of data.
