Formula & explanation
Seconds = file megabytes × 8 / megabits per second
Variables & units
- File size
- MB · minimum 0, maximum 1000000000000
- Connection throughput
- Mbit/s · minimum 0.000001, maximum 1000000000000
Worked example
1,000 MB over 100 Mbit/s takes at least 80 seconds.
Assumptions
Decimal MB (10⁶ bytes) and Mbit/s (10⁶ bits/s). Ideal constant throughput; excludes latency and protocol overhead.
Formula version 1.0.0. JavaScript floating-point arithmetic applies. Results display up to 6 decimal places; stored values retain available precision. Use the units shown.
