## How to Convert Knots to Kilometers per Second

To convert a measurement in knots to a measurement in kilometers per second, multiply the speed by the following conversion ratio: 0.000514 kilometers per second/knot.

Since one knot is equal to 0.000514 kilometers per second, you can use this simple formula to convert:

kilometers per second = knots × 0.000514

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

**For example,**here's how to convert 5,000 knots to kilometers per second using the formula above.

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

## What Is a Knot?

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.

## What Are Kilometers per Second?

Kilometers per second are a measurement of speed expressing the distance traveled 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.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.^{[2]} For example, km/s is expressing a change in length or distance relative to a change in time.

Kilometers per second can be expressed using the formula:

v_{km/s} = d_{km} / t_{sec}

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