How the conversion works

The relationship is c = kn × 1.716001956 × 10^-9. Both units measure speed, so the conversion is a fixed factor that never changes.

Speed of light: Exact by definition.

Common questions

How many times the speed of light are in one knot?
One knot equals 1.716 × 10^-9 times the speed of light. c = kn × 1.716001956 × 10^-9.
How do you convert knots to times the speed of light?
Use c = kn × 1.716001956 × 10^-9. So 10 kn is 1.716 × 10^-8 c.
How many knots are in one speed of light?
One speed of light equals 582,749,920 knots, which is the reverse of the conversion above.
Is there more than one kind of speed of light?
Exact by definition.
