About these measurements
Mass quantifies an amount of matter.
The base reference used here is the gram. One stone is 6,350.29318 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.
