  • Converts mass, not force. The result is the same on Earth or on the Moon.
  • Pounds and ounces are avoirdupois units. Troy ounces and the UK stone are not supported.
  • The ton is the metric ton (1,000 kg), not the US short ton or the UK long ton.
  • Results show up to 6 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.
