Overview
Convert between metric & imperial across categories
Australia adopted metric in 1974, but imperial units still appear in trades (inches for plumbing, feet for ladders), aviation (feet for altitude), and US-imported recipes. A reliable converter prevents costly mistakes.
Common conversions: 1 inch = 2.54 cm, 1 ft = 30.48 cm, 1 mile = 1.609 km, 1 lb = 0.4536 kg, 1 US gallon = 3.785 L, 1 imperial gallon = 4.546 L (yes, they differ).
