## How to Convert Speed Of Light to Knots

To convert a speed of light measurement to a knot measurement, multiply the speed by the conversion ratio.

Since one speed of light is equal to 582,749,918.35858 knots, you can use this simple formula to convert:

The speed in knots is equal to the speed of light multiplied by 582,749,918.35858.

**For example,**here's how to convert 5 speed of light to knots using the formula above.

Speed of light and knots are both units used to measure speed. Keep reading to learn more about each unit of measure.

## Speed Of Light

The speed of light is equal to exactly 299,792,458 meters per second, or 670,616,629 miles per hour.
The definition of the speed of light is actually derived from the most recent 1983 international definition of the meter.^{[1]}

Speed of light can be abbreviated as *c*; for example, 1 speed of light can be written as 1 c.

## Knots

One knot is equal to a speed of one nautical mile per hour,^{[2]} 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.
