How to calculate data transfer time
This calculator estimates data transfer time from file size and connection speed.
How the calculation works
Transfer time (seconds) = (File size in GB × 8000) ÷ Speed in Mbps. Multiplying by 8000 converts gigabytes to megabits (GB×8×1000) to match the Mbps unit.
Example
A 5 GB file at 100 Mbps: (5×8000)÷100 = 400 seconds ≈ 6.7 minutes.
Frequently asked questions
How is Result calculated?
Result = [File size] × 8000 ÷ [Transfer speed].

Pro Tips for Data Transfer Time
- Real-world transfer speeds are often lower than advertised connection speed due to network overhead — treat this as a best-case estimate.
- Confirm whether your speed figure is in Mbps (megabits) or MBps (megabytes) — these differ by a factor of 8, a common point of confusion.
Common Data Transfer Time Mistakes to Avoid
- Confusing Mbps (megabits per second) with MBps (megabytes per second), which differ by a factor of 8 and would produce a very wrong time estimate.
