Grain (gr) — a small imperial and US customary unit of mass
It is defined as exactly 1/7000 of an avoirdupois pound; since 1 lb = 0.45359237 kg exactly, 1 gr = 64.79891 mg exactly. Used mainly for measuring bullets, gunpowder, arrows, and some pharmaceutical or historical masses.
- Symbol: gr
- System: Imperial and US customary unit for mass
- Exact relations: 1 gr = 1/7000 lb = 1/437.5 oz = 64.79891 mg
- Metric equivalents: 1 gr = 0.06479891 g ≈ 0.0000647989 kg
- Typical examples: a small bullet ~40 gr; a larger rifle bullet ~150 gr; an aspirin tablet was historically 5 gr.
Quintal (q) — a metric unit of mass equal to 100 kilograms
It is commonly defined in the metric system as exactly 100 kilograms; historically, the word quintal has also been used for hundredweight-based units, so the exact value can depend on context. Used mainly in agriculture, trade, freight, and commodity measurements in countries where quintals are still common.
- Symbol: q
- System: Non-SI metric unit for mass; equal to 100 kilograms
- Exact relations: 1 q = 100 kg = 100,000 g = 0.1 t
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 q ≈ 220.462 lb ≈ 3527.40 oz
- Typical examples: crop yields may be measured in q per hectare; sacks of grain or rice can be counted in q; 10 q equals 1 metric ton.
