What this speed conversion is for

Use this page when a measurement is written in feet per second and the next step needs kilometers per second. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Multiply by the factor: 1 foot per second = 0.0003048 kilometers per second.

A worked example
