- 1 c = 29979245800 cm/s
- 1 × 29979245800 = 29979245800 cm/s
How to convert speed of light to centimeters per second
1 c = 29,979,245,800 cm/s, so multiply by 29,979,245,800 to go from speed of light to centimeters per second. Going the other way, 1 cm/s = 3.33564095198 × 10⁻¹¹ c.
cm/s = c × 29,979,245,800 c = cm/s × 3.33564095198
Worked example:
1 c = 29979245800 cm/s 5 × 29979245800 = 149896229000 cm/s
