Is this download time estimate exact?

No. It’s an estimate. Real downloads vary due to overhead, Wi‑Fi quality, congestion, and server limits.

Why is MB/s lower than Mbps?

Mbps is megabits per second. MB/s is megabytes per second. 1 byte = 8 bits, so MB/s is roughly Mbps ÷ 8 (before overhead).

It estimates how long it takes to download 650 MB at 250 Mbps.
