Knots to Kilometers per hour (kn to km/h)
Convert knots to kilometers per hour: 1 kn = 1.852 km/h. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 kn = 1.852 km/h
kilometers per hour = knots × 1.852 — reverse: knots = kilometers per hour × 0.5399568035
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.
Worked examples
- 5 kn = 9.26 km/h
- 12.5 kn = 23.15 km/h
- 100 kn = 185.2 km/h

FAQ
How many kilometers per hour are in one knot?
1 kn = 1.852 km/h. 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 kilometers per hour?
Multiply the value in knots by 1.852: kilometers per hour = knots × 1.852. For example, 5 kn = 9.26 km/h.
How do I convert kilometers per hour back to knots?
Multiply by the inverse factor 0.5399568035 (knots = kilometers per hour × 0.5399568035), or use the kilometers per hour-to-knots page.
