Transfer Speed Calculator

Calculate the effective transfer speed (Mbps and MB/s) from the data size and the time a download or upload took. Conversions to bps and Bps are shown at the same time.

How it works

  • Enter the amount of data transferred (choose from bit, B, KB, MB, GB, or TB) and the time it took (hours, minutes, seconds) to calculate the effective transfer speed automatically.
  • Speed is found by dividing the data size by the time. The main result is shown in Mbps, common for network connections, with MB/s shown as a familiar file-size reference.
  • Mbps is converted in decimal (1 million bits/s) following network industry convention, while MB/s uses binary (1024 x 1024 bytes/s) following file-size convention, so they are not a simple factor of 8 apart.
  • Conversions assume 1 byte = 8 bits, and the table also shows bps (bits per second), Bps (bytes per second), and the total bit count.
  • Enter your measured download or upload time to gauge your connection speed or check for slowdowns.
  • All input values are calculated in your browser only and are never sent to a server.
