How to convert feet to meters
m = x × 0.3048
The international foot is exactly 0.3048 m. This page accepts decimal feet: 5 feet 6 inches is 5.5 feet.
Worked example
m = 6 × 0.3048
6 ft = 1.8288 m.

Unit definitions and sources
Ordinary feet, yards and miles use international definitions. The separately labeled US survey foot is for legacy records only. A nautical mile is exactly 1,852 meters; it is not a constant minute of latitude on Earth.
| Unit and system | Use | Definition | Relationship |
|---|---|---|---|
| Meter (m); si | Common units | Meter measures length. m = (value in m) × 1. Common use: Dimensions and distances. | Exact definition; numerical display may be rounded |
| Foot (ft); us | Common units | Foot measures length. m = (value in ft) × 0.3048. Common use: Dimensions and distances. | Exact definition; numerical display may be rounded |

Precision of length conversions
These 2 length units convert through Meter (m). 2 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
