- 1 kn = 0.000514444444444 km/s
- 1 × 0.000514444444444 = 0.000514444444444 km/s
How to convert knots to kilometers per second
1 kn = 0.000514444444444 km/s, so multiply by 0.000514444444444 to go from knots to kilometers per second. Going the other way, 1 km/s = 1,943.84449244 kn.
km/s = kn × 0.000514444444444 kn = km/s × 1,943.84449244
Worked example:
1 kn = 0.000514444444444 km/s 5 × 0.000514444444444 = 0.00257222222222 km/s
