English: This files serves as a support to understand conversion from square meter to multiples of square meter. First, in the upper center, we define what a square meter is. In the upper left corner, we then show how to convert from square meter to square kilometer, and the reciprocal is below.

Originally, many thÆ°á»›c of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thÆ°á»›c of different lengths before 1890, [2] the thÆ°á»›c ta (lit. "our ruler") or thÆ°á»›c má»™c ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thÆ°á»›c Ä‘o vải ("ruler for measuring ...

A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
With the majority of the public now exposed to it since childhood, [7] the metric system became the sole legal measurement system in most fields of Japanese life on 1 January 1959. [4] Redrafting of laws to use metric equivalents had already been accomplished, but conversion of the land registries required until 31 March 1966 to complete.
A length of 100 kilometers (about 62 miles), as a rough amount, is relatively common in measurements on Earth and for some astronomical objects. It is the altitude at which the FAI defines spaceflight to begin. To help compare orders of magnitude, this section lists lengths between 100 and 1,000 kilometers (10 5 and 10 6 meters).
