Detailed Description

Standard integer-based types using int64_t representation.

For floating-point representations, use the alias templates, e.g. length<double>, length<double, std::milli> or volume<double, std::milli>.

Imperial and nautical precisions are exact ratios of one meter, from the international definitions: 1 in = 25.4 mm, 1 ft = 12 in, 1 yd = 3 ft, 1 mi = 5280 ft, 1 mil = 1/1000 in and 1 nmi = 1852 m. Area and volume precisions are exact ratios of one square or cubic meter: the squares and cubes of the length precisions, plus 1 ha = 1 hm², 1 acre = 43560 ft², 1 L = 1 dm³ and 1 US gallon = 231 in³.
