Also switchable to the following:
- grams, metric. Today everyone weighs gold in grams. But some UK dealers still like the answer in ounces (Troy ounces).
- Ounce Troy, for weighing precious metals (the same ounce that was once used for weighing mail, not the same ounce used for weighing food)
- ounce (some say, 'English' ounce, correct term is 'Avoirdupois' ounce) for food
- carat (ct) for gemstones and diamonds, not to be confused with carat as gold purity).
