Download Time Calculator
Calculate file transfer time while distinguishing megabits, megabytes, and binary storage units.
- Time, seconds
- 88.89
- Time, minutes
- 1.48
- Time, hours
- 0.025
How the calculation works
Seconds = file size in bytes × 8 / effective speed in bits per second.
Inputs
- File size
- Size unit
- Speed, Mbps
- Usable speed, %
Calculation details
MB and GB use powers of 1,000; MiB and GiB use powers of 1,024. One byte equals eight bits.
The usable-speed percentage allows for overhead. Pauses, server limits, and connection variation may increase transfer time.
