{Technical Specification}
RESOLUTION / CAPACITY: 50g / 0.001g, 100ct / 0.005ct, 250ct / 0.01ct
It's called "CT-250" because it weighs up to 250 carats for weighing diamonds (5ct = 1g).

Also switchable to ounces (oz), pennyweight (dwt), carat (ct), grains (gn)

- grams, metric. Today everyone weighs gold in grams. But dealers tend to weigh silver in Troy ounces.
- ounce (some say, 'English' ounce, correct term is 'Avoirdupois' ounce) for food
- Pennyweight (dwt), pre-decimal system, still used in USA
- Carat (ct) for gemstones and diamonds, not to be confused with carat as gold purity).
- Grains, originally used for weighing gold (based on a grain of wheat), today used for weighing powder

SIZE: in its carrying case with accessories 6 X 6.5 X 2 inches (145 X 170 X 50mm).
The balance: 5 X 3 X 1.75 inches (130 X 75 X 40mm).
