About these measurements

Mass quantifies an amount of matter.

The base reference used here is the gram. One milligram is 0.001 base units; one metric carat is 0.2 base units.

Important distinctions

Mass is not force. Avoirdupois ounces and troy ounces have different masses.

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.
