Gram (g) — a common SI unit of mass
It is defined as one thousandth of a kilogram, the SI base unit for mass; the kilogram is defined by fixing the Planck constant at exactly 6.62607015×10⁻³⁴ J·s. Used worldwide for measuring small amounts of mass in science, cooking, nutrition, medicine, commerce, and everyday life.
- Symbol: g
- System: SI unit for mass; decimal submultiple of the kilogram
- Exact relations: 1 g = 0.001 kg = 1000 mg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 g ≈ 0.03527396 oz ≈ 0.00220462 lb
- Typical examples: a paperclip ~1 g; a teaspoon of sugar ~4 g; a chocolate bar ~50 g.
Pennyweight (dwt) — a troy unit of mass for precious metals
It is defined as exactly 24 grains, or one twentieth of a troy ounce. Used mainly for measuring precious metals, jewelry, gemstones, dental alloys, and historical coin or bullion weights.
- Symbol: dwt
- System: Troy unit for mass
- Exact relations: 1 dwt = 24 gr = 1/20 oz t = 1.55517384 g
- Metric equivalents: 1 dwt = 1.55517384 g ≈ 0.00155517 kg
- Typical examples: small gold jewelry may weigh a few dwt; precious-metal scrap is often priced per dwt; 20 dwt equals 1 troy ounce.
