How the conversion works

The input is converted into kg using the source factor and offset, then into pennyweight. This keeps unit definitions consistent across the mass collection.

Definitions and sources

Factors are maintained in the versioned unit dataset. Output is rounded to your selected significant digits; calculation uses JavaScript double precision.

How to use this tool

  1. Enter a finite numeric value in milligram.
  2. Choose the significant digits for your result.

Accuracy and scope

Mass is not force. Ounce without a qualifier here means avoirdupois; troy units are explicitly labeled.
