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.
Metric ton (t) — a metric unit of mass equal to 1000 kilograms
It is defined as exactly 1000 kilograms; the metric ton is also called the tonne. Used worldwide for measuring large masses in shipping, industry, agriculture, construction, freight, commodities, and vehicle weights.
- Symbol: t
- System: Non-SI unit accepted for use with SI; equal to 1000 kilograms
- Exact relations: 1 t = 1000 kg = 1,000,000 g = 1,000,000,000 mg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 t ≈ 2204.62 lb ≈ 1.10231 US short tons ≈ 0.984207 UK long tons
- Typical examples: a small car ~1.5 t; a shipping container load can be tens of t; bulk grain or cement often measured in t.
