Complete tool guide
The Length Converter is a free online conversion tool for translating a length value from one measurement unit into another. Convert distances and dimensions between metric, imperial, and nautical units. Enter a number once to see the selected result and a comparison table covering every supported unit.
Unit conversion is useful whenever a specification, recipe, report, product label, instrument, dataset, or instruction uses a measurement system different from the one you need. The converter applies the defined mathematical relationship consistently and avoids the common mistakes caused by moving decimal points or relying on a remembered approximate factor.
Enter the source number exactly as supplied, including any required decimal precision.
Choose the original unit in the From field and verify its symbol; similarly named units can represent different quantities.
Choose the required destination unit in the To field and read the live result. Use Swap when you need the reverse relationship.
Review the all-conversions table, then copy the labeled result and retain the source value for traceability.
Metric, imperial, and nautical distances are converted through metres. Exact definitions include 1 inch = 25.4 mm, 1 foot = 0.3048 m, 1 mile = 1,609.344 m, and 1 nautical mile = 1,852 m.
All length values are normalized through metres using internationally defined exact factors.
This converter supports Millimetre (mm), Centimetre (cm), Metre (m), Kilometre (km), Inch (in), Foot (ft), Yard (yd), Mile (mi), Nautical mile (nmi).
The converted value expresses the same one-dimensional distance or size in a different unit; it does not change scale or physical length.
A length converter handles one-dimensional distance. Square and cubic measurements must use area or volume conversion because their factors are squared or cubed.
Displayed values are rounded for readability. A converted number cannot be more accurate than the source measurement, so do not treat extra decimal places as additional instrument precision.
Convert distances and dimensions between metric, imperial, and nautical units. Supported choices are Millimetre (mm), Centimetre (cm), Metre (m), Kilometre (km), Inch (in), Foot (ft), Yard (yd), Mile (mi), Nautical mile (nmi). Select the unit attached to the source value and the unit required for the result.
The calculator uses the factors and formulas described above and retains precision internally. The practical accuracy still depends on the source measurement, correct unit selection, displayed rounding, and whether the context uses the same unit definition.
Check for a rounded factor, a different regional unit, an incorrect source unit, or a distinction such as decimal versus binary, US versus imperial, gauge versus absolute, or mass versus volume. Compare the complete unit name and method.
Only some metric-prefix conversions work that way. Imperial relationships, offset temperature scales, reciprocal fuel economy, area, volume, and many cross-system conversions require specific formulas. Use the defined converter rather than assuming a power of ten.
