Why units matter for precious metals
Bullion is priced in troy ounces, jewelry in grams, South Asian markets in tolas and Chinese markets in taels. Mixing up the avoirdupois ounce (28.35 g) and troy ounce (31.10 g) is a common 9.7% error when comparing prices.
- Ask sellers which ounce they mean.
- Convert everything to grams before comparing offers.
- Use the exact factors on this page rather than rounded ones for large amounts.
