This free length and distance converter handles the most common unit conversions between the metric system (metres, kilometres, centimetres, millimetres) and the imperial system (feet, inches, yards, miles). Every pair of inputs is bidirectional — type a value in either box and the opposite updates instantly.
Construction & renovation: Australian building plans use millimetres and metres, but many imported tools, timber sizes, and hardware fittings still use imperial measurements. Quickly checking that 2×4 lumber is 38 × 89 mm can save costly mistakes on site.
Height measurement: Most of the world uses centimetres, but many countries — including the US and UK — still list height in feet and inches. If you're 175 cm tall, that's 5 feet 9 inches. This converter makes the check instant.
Travel & navigation: Road signs in the US, UK, and a handful of other countries display distances in miles. If you're used to kilometres, knowing that a 100 km drive is roughly 62 miles helps you plan fuel stops and travel times accurately.
International shopping: Clothing, screen sizes, and furniture dimensions are often listed in inches on US or UK retail sites. Converting to centimetres helps you verify fit before buying.
Not exactly. One mile is precisely 1.60934 km. The commonly used "1.6 km" is a convenient approximation. For navigation and fuel calculations, use the exact figure for best accuracy.
A metre is 3.28084 feet; a yard is exactly 3 feet (0.9144 m). So a metre is just slightly longer than a yard — about 9.36 cm longer.
