How does this calculator work?
Divide grams by 28.3495 for avoirdupois ounces (everyday use) or by 31.1035 for troy ounces (precious metals). Equivalently multiply by 0.03527 or 0.03215 respectively. One pound equals 453.592 g or 16 avoirdupois ounces.
Formula
How this is calculated
The avoirdupois ounce is the standard ounce used for food, postal weights, and most everyday goods in the United States, United Kingdom, and Canada. One avoirdupois ounce equals exactly 28.349523125 grams, defined by international treaty. Converting grams to ounces is therefore simply dividing by 28.349523125 (or equivalently multiplying by 0.035274).
The troy ounce is a separate, slightly heavier unit (31.1034768 g) used exclusively for precious metals — gold, silver, platinum, and palladium. When a jeweller or bullion dealer quotes a price "per ounce," they invariably mean the troy ounce. The two systems also differ in how pounds are defined: a troy pound is 12 troy ounces (373.24 g), whereas an avoirdupois pound is 16 avoirdupois ounces (453.59 g). The pound shown by this calculator is always the avoirdupois pound.
All conversions use exact legal definitions with no rounding error in the multipliers. Inputs must be non-negative — mass cannot be negative in everyday measurement contexts. For very large values the scale bar is capped at 500 g for readability; the calculated figures are exact regardless of scale position.
Frequently asked questions
One avoirdupois ounce (the everyday kind) equals exactly 28.349523125 grams. One troy ounce (used for precious metals) equals 31.1034768 grams — about 10 % heavier.
A troy ounce (31.1035 g) is used only for precious metals such as gold and silver. A regular (avoirdupois) ounce (28.3495 g) is used for everything else — food, body weight, postage. When buying or selling gold, always confirm whether the price is quoted in troy ounces.
Divide by 28.35 — but a handy shortcut is to multiply by 0.035: 100 g × 0.035 = 3.5 oz (the precise answer is 3.5274 oz avoirdupois). For troy ounces divide by 31.1 instead.
