Speed of Light: Calculate distance or time

Speed of light calculator for the distance per time or time per distance.

distance = speed of light * time
s = c * t

Speed of Light: meters per second, m/s

Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days).

Examples: the average distance of the moon from earth is 384400 kilometers. The light takes just under 1.3 seconds to get there.

For one centimeter, light takes 3.3e-11 seconds. These are 0.000000000033 seconds (first digit ≠0 at the 11. decimal place).

The calculators use . and , als decimal separators.
