About This Calculator

Download time is file size in megabits divided by link speed in Mbps. This calculator converts MB to megabits (×8) so advertised internet speed matches the file size unit.

Time

seconds = (file size MB × 8) / speed Mbps

1500 MB at 50 Mbps → 240 seconds (4 minutes), ignoring overhead.
