How to Convert Knots to Kilometers Per Second

Speedometers are used in vehicles to measure speed

To convert a knot measurement to a kilometer per second measurement, multiply the speed by the conversion ratio. One knot is equal to 0.000514 kilometers per second, so use this simple formula to convert:

kilometers per second = knots × 0.000514

The speed in kilometers per second is equal to the knots multiplied by 0.000514.

For example, here's how to convert 5 knots to kilometers per second using the formula above.
5 kn = (5 × 0.000514) = 0.002572 km/s

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

Knots

One knot is equal to a speed of one nautical mile per hour, 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.

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.
