About these measurements
Acceleration is the rate of velocity change.
The base reference used here is the meter per second squared. One millimeter per second squared is 0.001 base units; one inch per second squared is 0.0254 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 mm/s² to in/s²?
