How to convert centimeters per second to speed of light

1 c = 29,979,245,800 cm/s, so divide by 29,979,245,800 to go from centimeters per second to speed of light (1 cm/s = 3.33564095198 × 10⁻¹¹ c).

c = cm/s ÷ 29,979,245,800
cm/s = c × 29,979,245,800

Worked example:

1 cm/s = 3.33564095198e-11 c
5 × 3.33564095198e-11 = 1.66782047599e-10 c
