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 hour is 0.0001259978806 base units; one gram per second is 0.001 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.
