Convert kilometers per hour (km/h) to kilometers per second (km/s) with formulas, examples, and conversion tables.
To convert 1 kilometers per hour to kilometers per second, we divide by 3600 because one kilometer per second equals exactly 3600 kilometers per hour.
Since there are 3600 kilometers per hour in every kilometer per second, we divide our value by this factor:
So 1 kilometers per hour = 0.0003 kilometers per second.
To convert kilometers per hour to kilometers per second, divide the value by 3600.
1 kilometer per second = 3600 kilometers per hour
