Mount Fuji is 3.776 kilometres (2.346 mi) high. The kilometre (SI symbol: km) is a unit of length in the metric system equal to 1 000 meters (10 3 m). To help compare different orders of magnitude, this section lists lengths between 1 kilometer and 10 kilometers (10 3 and 10 4 meters).
Simple meters are those whose upper number is 2, 3, or 4, sometimes described as duple meter, triple meter, and quadruple meter respectively. In compound meter , the note values specified by the bottom number are grouped into threes, and the upper number is a multiple of 3, such as 6, 9, or 12.

The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299 792 458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
Triple metre (or Am. triple meter, also known as triple time) is a musical metre characterized by a primary division of 3 beats to the bar, usually indicated by 3 or 9 in the upper figure of the time signature, with 3 4, 3 8 and 9 8 being the most common examples. In these signatures, beats form groups of three, establishing a triple meter feel ...
The most popular of these is the rachenitsa, a type of khoro in a rapid septuple meter divided 2+2+3. In the Pirin area, the khoro has a rhythm subdivided 3+2+2 , and two varieties of it are the pravo makedonsko ("straight Macedonian") and the mazhka rachenitsa ("men's rachenitsa").
4, is assumed to either be equivalent to a measure of 3 4 followed by a measure of 2 4, or the opposite: 2 4 then 3 4. Higher metres which are divisible by 2 or 3 are considered equivalent to groupings of duple or triple metre measures; thus, 6 4, for example, is rarely used because it is considered equivalent to two measures of 3 4.
In 1983 this was updated to a length defined in terms of the speed of light; this definition was reworded in 2019: [3] The metre, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m⋅s −1 , where the second is defined in terms ...
