Formula and method
This calculator computes Time, Time directly in your browser without sending data to an external server.
Mathematical formula
- Time:
size × 8 × 1024 ÷ speed ÷ 60 - Time:
size × 8 × 1024 ÷ speed ÷ 3600
Variables and parameters
- File size (size): default value 10 GB.
- Connection speed (speed): default value 100 Mbps.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
Examples
- Example: with File size = 10 GB, Connection speed = 100 Mbps, this calculator returns Time = 13.65 minutes, Time = 0.23 hours.
