Full precision:0.00027778 km/s
Step-by-Step Solution
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.
1 kilometer per second = 3600 kilometers per hour
Since there are 3600 kilometers per hour in every kilometer per second, we divide our value by this factor:
1 ÷ 3600 = 0.000278 kilometers per second
So 1 kilometers per hour = 0.000278 kilometers per second.
Quick check: 0.000278 × 3600 = 1 kilometers per hour
