Common mass conversion mistakes

  • The everyday avoirdupois ounce is about 28.35 g, but precious metals are priced in troy ounces of about 31.10 g. An 'ounce of gold' is nearly 10% heavier than an ounce of flour. Use troy ounces for gold and silver, the regular ounce for everything else.
  • The 'just double it' shortcut from kilograms to pounds hides a 10% error: a kilogram is about 2.205 lb, so 80 kg is 176 lb, not 160. Multiply by 2.2 instead: double the number, then add 10%.
