Quick answer

On this site, 1 Hong Kong tael = 37.429 grams and 1 troy ounce is about 31.1035 grams. Convert products and quotes to one unit before comparing them.

Useful formulas

Grams to taels: divide by 37.429. Taels to grams: multiply by 37.429.

Precious metals use the troy ounce, so an everyday ounce is the wrong basis.

  • 1 tael = 37.429 g
  • 1 troy ounce ≈ 31.1035 g
  • 1 kilogram = 1,000 g

What conversion does not tell you

Conversion does not account for fineness, whether you are buying or selling, product premiums or buyback terms.

For corporate or large transactions, retain original weights, converted weights and quote timestamps for review.
