Knots to Speed Of Light Conversion
Enter the speed in knots below to get the value converted to speed of light.
How to Convert Knots to Speed Of Light
To convert a knot measurement to a speed of light measurement, multiply the speed by the conversion ratio.
Since one knot is equal to 1.716E-9 speed of light, you can use this simple formula to convert:
The speed in speed of light is equal to the knots multiplied by 1.716E-9.
Knots and speed of light 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,[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.
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.[2]
Speed of light can be abbreviated as c; for example, 1 speed of light can be written as 1 c.
