Speed Converters
Convert speed as distance per unit time with meters per second (m/s) as the SI reference. This hub covers common road units (km/h and mph), engineering units (ft/s), and nautical speed in knots.
Explanation
Speed is distance per unit time. The SI reference m/s is derived from the base units meter and second, and every conversion is computed by reducing both units to m/s. Ratios are purely multiplicative with no offsets, and knots are defined as nautical miles per hour. For clarity, speed conversions are grouped by SI normalization and common transport measurement systems.
The Speed hub maps related converter families into directional routes with consistent assumptions.

Frequently Asked Questions
Why is m/s used as the base reference?
Meters per second is the SI derived speed unit from the base units meter and second, so it provides a consistent common reference for every speed pair.
What is a knot exactly?
A knot is one nautical mile per hour, used primarily in marine and aviation navigation.
Are these speed conversions exact?
Yes. The factors come from fixed definitions of distance and time units and are computed through m/s without offsets.
Why are different speed systems used?
Different sectors standardize different units: km/h for road transport, mph and ft/s in many US contexts, and knots for marine and aviation operations.
