Convert knots to km/s and km/s to knots instantly. Bidirectional speed converter with formula and common values.

kn

Kilometers per Second

1.0001

km/s

1944 kn = 1.0001 km/s

km/s = kn × 0.000514444

Knots to Kilometers per Second: 1 kn equals 0.000514 km/s. To convert knots to kilometers per second, multiply by 0.000514 (km/s = kn × 0.000514444). For example, 10 kn = 0.005144 km/s.

How to Convert Knots to Kilometers per Second

To convert from knots to kilometers per second, multiply the value by 0.000514. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Knots to Kilometers per Second: km/s = kn × 0.000514444
  • Kilometers per Second to Knots: kn = km/s ÷ 0.000514444
