How to Convert Kilometers Per Second to Knots

Speedometers are used in vehicles to measure speed

To convert a kilometer per second measurement to a knot measurement, multiply the speed by the conversion ratio. One kilometer per second is equal to 1,943.844492 knots, so use this simple formula to convert:

knots = kilometers per second × 1,943.844492

The speed in knots is equal to the kilometers per second multiplied by 1,943.844492.

For example, here's how to convert 5 kilometers per second to knots using the formula above.
5 km/s = (5 × 1,943.844492) = 9,719.222462 kn

Kilometers per second and knots are both units used to measure speed. Keep reading to learn more about each unit of measure.

Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance travelled in kilometers in one second.

The kilometer per second, or kilometre per second, is an SI unit of speed in the metric system. Kilometers per second can be abbreviated as km/s, and are also sometimes abbreviated as km/sec. For example, 1 kilometer per second can be written as 1 km/s or 1 km/sec.

Kilometers per second can be expressed using the formula:
vkm/s = dkmtsec

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.

Knots

One knot is equal to a speed of one nautical mile per hour,[1] or one minute of latitude per hour.

Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.
