Length Converter translates measurements across metric and imperial units — millimetres, centimetres, metres, kilometres, inches, feet, yards, and miles — instantly and accurately.
Its value comes from the awkward gap between the two systems. Metric is decimal, scaling cleanly by powers of ten, while imperial uses irregular factors (12 inches to a foot, 1,760 yards to a mile) that make cross-system maths error-prone. The converter handles those factors so you don't have to remember them.
The conversions are exact because the key factor is defined precisely: one inch is exactly 2.54 cm, from which a foot (30.48 cm) and yard (91.44 cm) follow. Handy mental estimates — 1 m ≈ 3.3 ft, 1 km ≈ 0.6 mi — are useful on the fly, but the tool gives the precise value when it matters.
Conversion runs in your browser with nothing uploaded. Pair it with the Weight, Temperature, and other ToolsMonk unit converters for DIY, travel, study, and everyday reference.
Quick estimates: 1 inch ≈ 2.5 cm, 1 m ≈ 3.3 ft, 1 km ≈ 0.6 mi
Metric scales by tens; imperial doesn't — let the converter handle the irregular imperial factors
1 inch = 2.54 cm exactly, so inch↔cm conversions are precise, not rounded
