Estimate transfer time with decimal bytes and network bit rates.
Your numbers
Estimated duration
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use t = 8000G/(vη). G is the file size in decimal GB, v is the link speed in Mbps, η is the efficiency fraction, and t is seconds.

Scope and limitations
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
