About Volume Units
- The cubic metre (m³) is the SI unit of volume. The litre (L) is a derived unit defined as exactly 1 dm³ (= 0.001 m³), widely used for liquids and gases in everyday and industrial contexts. 1 mL = 1 cm³.
- The US liquid gallon (gal) is defined as exactly 231 cubic inches (≈ 3.785 L). The oil barrel (bbl) equals 42 US gallons (≈ 159 L) — established by the US petroleum industry in the 1860s and now the global standard unit for crude oil trading.
- The board foot (FBM — Foot Board Measure) is a lumber-specific volume unit: 1 FBM = 1 ft × 1 ft × 1 in = 144 in³ ≈ 2.360 L. It measures the nominal volume of sawn timber before drying and finishing.
- Quick reference: 1 m³ = 1,000 L = 35.315 ft³ = 264.17 gal · 1 ft³ = 28.317 L = 7.481 gal · 1 bbl = 42 gal = 158.99 L.
