At a glance:Convert the file to bits (MB×8×10⁶, GB×8×10⁹) and speed to bits/s (Mbps×10⁶, MB/s×8×10⁶); time = file bits ÷ speed bits.
Formula
bits = fileSize × (MB:8×10⁶ / GB:8×10⁹).
bps = speed × (Mbps:10⁶ / MBps:8×10⁶).
seconds = bits ÷ bps; minutes = seconds ÷ 60.
How to Use
- Choose the size unit and speed unit, then enter the values.
- Get seconds and minutes instantly.
FAQ
Mbps vs MB/s?
1 MB/s = 8 Mbps; ISPs usually quote Mbps while download tools show MB/s — an 8× difference.
Why is it faster than real life?
Real transfers suffer congestion and protocol overhead; this is a theoretical maximum.
