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.
Obolus (obol) — a historical unit of mass equal to 10 grains
It is commonly treated as half a scruple, or 10 grains, in historical Roman and apothecaries’ weight contexts; because the obolus was also a coin and ancient weight term, its exact value can vary by period and region. Used mainly in historical medicine, pharmacy, numismatics, and references to ancient or apothecaries’ measures.
- Symbol: obol, obolus
- System: Historical Roman and apothecaries’ unit for mass
- Exact relations: 1 obolus = 1/2 scruple = 10 gr = 647.9891 mg
- Metric equivalents: 1 obolus = 0.6479891 g ≈ 0.000647989 kg
- Typical examples: historical prescriptions may mention oboli; 2 oboli equals scruple; 1 obolus is a little less than 2/3 of a gram.
