Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Confusing international foot (0.3048 m) with legacy ‘US survey foot’ in old datasets.
- Rounding mid-calculation; keep precision to the end.
Unit facts
- Nautical mile (nmi): A nautical mile is exactly 1,852 meters—one minute of arc along a meridian. Basis for speed in knots.
- Foot (ft): The foot is exactly 0.3048 meters (1959). Common in construction, aviation (runway lengths), and everyday use in US/UK.
About Length
Length measures distance or size. In SI it derives from the meter, defined via the speed of light, which ensures exact, reproducible conversions. Typical applications include construction, mapping, manufacturing tolerances, and navigation; legacy units like inches and feet remain common in trade and building plans.
About Nautical mile (nmi)
Nautical mile (nmi)
Exactly 1,852 meters. Preferred in maritime and aviation because it links to Earth geometry (minutes of arc). Knots (nmi/h) derive from it.
History: Standardized by the International Hydrographic Organization in 1929; earlier definitions tied 1 nmi to 1 minute of latitude varying slightly with geodetic model.
About Foot (ft)
Foot (ft)
Equals 12 inches; exactly 0.3048 m. Common for human height, room dimensions, and altitude in aviation (with feet for flight levels).
History: Standardized as the ‘international foot’ in 1959; the legacy US survey foot persisted for geodesy until its retirement in 2023 in favor of the international definition.
