How to Convert Knots to Speed Of Light

Speedometers are used in vehicles to measure speed

To convert a knot measurement to a speed of light measurement, multiply the speed by the conversion ratio. One knot is equal to 1.716E-9 speed of light, so use this simple formula to convert:

speed of light = knots × 1.716E-9

The speed in speed of light is equal to the knots multiplied by 1.716E-9.

For example, here's how to convert 5 knots to speed of light using the formula above.
5 kn = (5 × 1.716E-9) = 8.58E-9 c

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