Examples
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.
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 Centimeter (cm)
Centimeter (cm)
Equals 1/100 of a meter. Ubiquitous in everyday measuring, crafts, medical records (height), and technical drawings. Offers a good balance between precision and readability.
History: Part of the decimal ladder of the metric system introduced after the French Revolution. Its popularity grew with mass education and standardized rulers.
