Inch / Nautical Mile Units Definition
Inch
The inch (symbol: ″ (double prime) or po in French-speaking Canada) is a unit of length dating back to the Middle Ages.Its dimensional value has varied over time, across regions and across countries.Since 1959, following an English compromise, the English inch — also called the “international technical inch” — has been exactly 2.54 cm, or one twelfth of a foot or one thirty-sixth (1⁄36) of a yard. For historical reasons, other definitions of the inch are still in force in certain areas.
Nautical Mile
The nautical mile (symbol Ma, NMb, nm, nmi or Nqc) is a unit of measurement of length used in maritime and air navigation, equal by convention to 1,852 metersd, Although not part of the International System of Units, the nautical mile is linked to it since it is defined in relation to the meter2. Historically, it has the average value of a minute of latitude of an arc of a meridian, i.e. 1,851.85 m, which has been rounded by convention to 1,852 m3.
