- 72 inches (6 feet) = 182.88 cm
Australians convert inches to centimetres when reading US product specifications, checking tyre profiles, or understanding international clothing sizes. Building materials imported from the US may use inch-based dimensions that need converting for Australian metric floor plans.
Australian building codes (the National Construction Code) are entirely metric. However, some imported power tools and plumbing fittings still carry inch-based designations. Drill bits are sold in metric mm sizes in Australia, whereas US hardware stores use fractions of an inch.
