km/h to cm/s Converter - Kilometer per Hour to Centimeter per Second
Kilometer per Hour (km/h) to Centimeter per Second (cm/s)
Direct answer
1 km/h = 27.7778 cm/s
cm/s = km/h × 27.7778
Converter
Conversion formula
cm/s = km/h × 27.7778
km/h = cm/s × 0.0359999712
Example: 10 km/h = 10 × 27.7778 = 277.778 cm/s.

Conversion Factor: Kilometer per Hour to Centimeter per Second
The conversion factor between kilometer per hour (km/h) and centimeter per second (cm/s) is derived by expressing both units in the common base unit of meter per second (m/s). This allows the numerical relationship to be determined by the ratio of their respective base unit equivalents.
Definition
1 kilometer per hour (km/h) is equivalent to 27.7778 centimeters per second (cm/s). 1 centimeter per second (cm/s) is equivalent to 0.0359999712 kilometer per hour (km/h).
Principle
The conversion is performed by first converting the given unit to the base unit (m/s) and then converting that base unit value to the target unit. The factor is the ratio of the base unit equivalents.
Assumptions
- The conversion uses the exact base unit equivalences: 1 km/h = 0.277778 m/s and 1 cm/s = 0.01 m/s.
- The calculation is performed without intermediate rounding.
Cautions
- The reverse conversion factor is provided to a high precision. The forward factor of 27.7778 is the more commonly used value.
- Results should be rounded to the precision required by the specific calculation.
