Carat (ct) — a metric unit of mass for gemstones
It is defined as exactly 200 milligrams, or one fifth of a gram. Used worldwide for measuring diamonds, gemstones, pearls, and other jewels; it should not be confused with karat, which measures gold purity.
- Symbol: ct
- System: Non-SI metric unit for mass; used with SI
- Exact relations: 1 ct = 200 mg = 0.2 g = 0.0002 kg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 ct ≈ 0.00705479 oz ≈ 0.000440925 lb
- Typical examples: a small diamond ~0.25 ct; an engagement-ring diamond ~1 ct; large gemstones may be several ct.
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.
