About these measurements
Density is mass per unit volume.
The base reference used here is the kilogram per cubic meter. One ounce per cubic inch is 1,729.994044 base units; one pound per cubic foot is 16.01846337 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.
