Meter / Nautical Mile Units Definition
Meter
The meter is the unit of measurement par excellence since the origin of this unit comes from the Latin "metrum" and the Greek "metron" which mean measure. It is also this unit which gives its name to the diplomatic treaty which formalizes the decimal metric system: the convention of the meter, signed on May 20, 1875 by 17 nations, which today provides its basis for the International System of Units (SI).
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.
