Speed Conversions — All 5 Units

ConvBolt Unit Converter · Updated 2026-10-04

Speed covers 5 units — m/s, km/h, mph, kn, ft/s. This page is the map for the family: every unit below links to a hub that lists its conversions to all the others, and each conversion has its own page with the exact factor, a value table and a worked example.

The pages here are generated from fixed conversion factors, so a number you get from a table, from a hub or from the on-page calculator is always the same. Nothing is rounded behind the scenes and no value depends on which page you started from.
