About these measurements
Mass flow rate measures mass passing a point per unit time.
The base reference used here is the kilogram per second. One pound per second is 0.45359237 base units; one kilogram 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.
