How it works
- Supports the metric system—millimeter (mm), centimeter (cm), meter (m) and kilometer (km)—the imperial and nautical units inch (in), foot (ft), yard (yd), mile (mi) and nautical mile (M), the Japanese shakkanho units shaku, sun and ken, plus the light-year (ly) and angstrom (Å).
- The base unit for conversion is the meter (m). Your input is first converted to meters, then divided back by each unit's defined conversion factor to compute the value in every unit.
- To use it, type the number you want to convert in the field above and choose its unit from the dropdown. The table below shows the converted value in all units, including the one you selected, at the same time.
- Conversions use exact definition values (e.g. 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 mile = 1609.344 m, 1 nautical mile = 1852 m, 1 shaku = 10/33 m, 1 ken = 6 shaku). The light-year is based on the Julian year (365.25 days) and the speed of light.
- Very large or very small numbers are shown in exponential notation; otherwise values are displayed to roughly six decimal places. Displayed values are rounded approximations, so mind the remainder for exact calculations.
