How to Convert Speed of Light to Knots
To convert a measurement in speed of light to a measurement in knots, multiply the speed by the following conversion ratio: 582,749,918.35858 knots/speed of light.
Since one speed of light is equal to 582,749,918.35858 knots, you can use this simple formula to convert:
knots = speed of light × 582,749,918.35858
The speed in knots is equal to the speed in 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.
knots = (5 c × 582,749,918.35858) = 2,913,749,591.7929 kn
Speed of light and knots are both units used to measure speed. Keep reading to learn more about each unit of measure.
What Is the 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.

What Is a Knot?
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.
