·         It has mode selections to measure in:

Grams
Carats
Penny Weight - dwt (used in gold measurements, 18.23 dwt = 1 Ounce or avoirdupois)
Grains - gn (some pharmaceuticals still use this measurement, aspirin for instance)
Ounces - oz (Don't mix this up with troy ounces, which it also measures)
Troy Ounce - ozt (Troy ounce, used when measuring precious metals it is equal to 31 grams instead of 28 like a normal ounce)

The accessories are of okay quality and the calibration masses check out to within 0.00025 grams of 10g and each other - there is a place for one of the check weights on the scale itself and one in the carrying case which is a little silly.
