Milligram (mg) — a small SI unit of mass
It is defined as one thousandth of a gram, or one millionth of a kilogram, the SI base unit for mass. Used worldwide for measuring very small masses in medicine, nutrition, chemistry, laboratory work, supplements, and precise product labeling.
- Symbol: mg
- System: SI unit for mass; decimal submultiple of the kilogram
- Exact relations: 1 mg = 0.001 g = 0.000001 kg = 1000 µg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 mg ≈ 0.000035274 oz ≈ 0.00000220462 lb
- Typical examples: a medicine dose ~200 mg; a vitamin tablet ~500 mg; a small grain of salt less than 1 mg.
Denarius (denarius) — a historical Roman unit of mass and silver coin
It was originally a Roman silver coin rather than a modern fixed mass unit; historical denarius weights varied by period, while modern biblical or historical unit converters commonly use about 3.85 grams. Used mainly in numismatics, ancient history, biblical studies, historical trade, and references to Roman coin weights.
- Symbol: denarius
- System: Historical Roman and biblical unit for mass
- Common conversion: 1 denarius ≈ 3.85 g = 3850 mg ≈ 0.00385 kg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 denarius ≈ 0.135805 oz ≈ 0.00848777 lb
- Typical examples: early Roman silver denarii weighed around 4 g; later coin weights changed over time; biblical and historical converters often use about 3.85 g.
