Length tools
Convert between metric, imperial and nautical length units. Since the 1959 International Yard and Pound Agreement the inch has been exactly 25.4 mm, which makes every metric-to-imperial length conversion an exact arithmetic operation rather than an estimate.
About length conversion
Length is the most fundamental of the measured quantities, and the meter is its SI base unit. Every unit below — metric, imperial or nautical — is now defined as an exact multiple of the meter, so conversions between them are exact rather than approximate.
