How to Convert Kilometers Per Second to Kilometers Per Hour Using an Easy Conversion Formula

Speedometers are used in vehicles to measure speed

Convert kilometers per second to kilometers per hour with this simple formula:

kilometers per hour = kilometers per second × 3,600

Converting a kilometer per second speed measurement to a kilometer per hour measurement involves multiplying your speed by the conversion ratio to find the result. A kilometer per second is equal to 3,600 kilometers per hour, so to convert simply multiply by 3,600.

For example:
5 km/sec = (5 × 3,600) = 18,000 km/h

Kilometers per second and kilometers per hour are both units used to measure speed. Learn more about speed and find more speed measurement conversion calculators. A kilometer per second is a metric measurement and can be abbreviated as km/sec, for example 1 km/sec. A kilometer per hour is a metric measurement and can be abbreviated as km/h, for example 1 km/h.
