Speed Converter

Convert common land, engineering, and marine speed units through meters per second. Each result is a unit conversion, not a route or travel-time estimate.

Reference conversions

Source unitEquivalent
1 km/h0.2777777778 m/s
1 mph0.44704 m/s
1 foot per second0.3048 m/s
1 knot0.514444444 m/s

Worked example

100 km/h = 27.77777778 m/s = 62.13711922 mph = 53.99568039 kn.

Important interpretation

A knot is one nautical mile per hour. Do not substitute a statute mile when checking marine or aviation speeds.

Usage boundaries and result checks

Speed Converter is for this task: Convert m/s, km/h, mph, ft/s, and knots quickly. It runs in the browser; start with a short, non-sensitive sample and confirm the behavior before processing more data.

Best use

Use it for a focused Speed Converter task when a quick browser workbench is appropriate.
