Knots to Meters per second (kn to m/s)

Convert knots to meters per second: 1 kn = 0.514444 m/s. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

Formula

1 kn = 0.514444 m/s

meters per second = knots × 0.5144444444 — reverse: knots = meters per second × 1.943844492

The factor is derived from the SI definitions of both units (base unit: m/s) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

FAQ

How many meters per second are in one knot?

1 kn = 0.514444 m/s. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

What is the formula to convert knots to meters per second?

Multiply the value in knots by 0.5144444444: meters per second = knots × 0.5144444444. For example, 5 kn = 2.57222 m/s.

How do I convert meters per second back to knots?

Multiply by the inverse factor 1.943844492 (knots = meters per second × 1.943844492), or use the meters per second-to-knots page.
