1 km/s = 1943.84449244 kn
1 × 1943.84449244 = 1943.84449244 kn

How to convert kilometers per second to knots

1 km/s = 1,943.84449244 kn, so multiply by 1,943.84449244 to go from kilometers per second to knots. Going the other way, 1 kn = 0.000514444444444 km/s.

kn = km/s × 1,943.84449244
km/s = kn × 0.000514444444444

Worked example:

1 km/s = 1943.84449244 kn
5 × 1943.84449244 = 9719.2224622 kn
