Convert kilometers per second (km/s) to speed of light (c) with formulas, examples, and conversion tables.
To convert 1 kilometers per second to speed of light, we divide by 299792.46 because one speed of light equals exactly 299792.46 kilometers per second.
Since there are 299792.46 kilometers per second in every speed of light, we divide our value by this factor:
So 1 kilometers per second = 3.3356e-6 speed of light.
To convert kilometers per second to speed of light, divide the value by 299792.46.
1 speed of light = 299792.46 kilometers per second
