Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is in-between 1 meter to 1 millimeter.. A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 / 100 . [1]
The United States adopted the conversion factor 1 metre = 39.37 inches by an act in 1866. [30] In 1893, Mendenhall ordered the physical realization of the inch to be based on the international prototype metres numbers 21 and 27, which had been received from the CGPM, together with the previously adopted conversion factor. [31]
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...

This differs from many older systems in which the ratio of different units varied. For example, 12 inches is one foot, but the larger unit in the same system, the mile is not a power of 12 feet. It is 5,280 feet – which is hard to remember for many. [5]: 17
A child's size zero is equivalent to 4 inches (a hand = 12 barleycorns = 10.16 cm), and the sizes go up to size 13 + 1 ⁄ 2 (measuring 25 + 1 ⁄ 2 barleycorns, or 8 + 1 ⁄ 2 inches (21.59 cm)). Thus, the calculation for a children's shoe size in the UK is: child shoe size (barleycorns) = 3 × last length (in) − 12. equivalent to:

Traditionally, the actual length of the shaku varied over time, location, and use. By the early 19th century, the shaku was largely within the range of 0.30175 to 0.303 meters (11.880 in to 11.929 in), [1] but a longer value of the shaku (also known as the kōrai-shaku) was also known, and was 1.17 times longer than the present value (35.5 centimeters or 14.0 inches).
