About these measurements
Acceleration is the rate of velocity change.
The base reference used here is the meter per second squared. One kilometer per hour second is 0.2777777778 base units; one meter per second squared 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 km/(h·s) to m/s²?
Multiply the quantity in km/(h·s) by 0.2777777778. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the meter per second squared to kilometer per hour second converter.
