kilogram kilometer per hour to kilogram meter per second
Convert kilogram kilometer per hour (kg·km/h) to kilogram meter per second (kg·m/s). Use an editable momentum converter, conversion formula, and reference table.
1 kg·km/h = 0.2777777778 kg·m/s
Conversion formula
One kilogram kilometer per hour equals 0.2777777778 kilogram meter per second. Multiply your value in kilogram kilometer per hour by this factor to get kilogram meter per second. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 kilogram kilometer per hour:5 × 0.2777777778 = 1.388888889 kg·m/s

About these measurements
Momentum is mass multiplied by velocity.
The base reference used here is the kilogram meter per second. One kilogram kilometer per hour is 0.2777777778 base units; one kilogram meter per second is 1 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert kg·km/h to kg·m/s?
