The hectometre, (SI symbol: hm [1]), spelt hectometer in American and Philippine English, is a unit of length in the International System of Units (SI), equal to one hundred metres [2] and to one tenth of a kilometre. The word comes from a combination of "metre" and the SI prefix "hecto-", meaning "hundred". [3] It is not commonly used in English.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10 −2 metres ( 1 / 100 m = 0.01 m). To help compare different orders of magnitude , this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm).
[1] [2] Its unit symbol as an SI prefix in the International System of Units (SI) is the lower case letter h. The prefix is rarely used in general, but has certain specific applications: hectopascal (hPa), in meteorology , for atmospheric pressure , the modern equivalent of the traditional millibar .

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 .

Spatial frequency is a reciprocal length, which can thus be used as a measure of energy, usually of a particle. For example, the reciprocal centimetre, cm −1, is an energy unit equal to the energy of a photon with a wavelength of 1 cm. That energy amounts to approximately 1.24 × 10 −4 eV or 1.986 × 10 −23 J.
[2] [38 Dutch gallons, 129 L iters, 31.6572 (≈32) Imp. gals.] An ahm (anglicised as "aum" - using the French spelling) was a Dutch and German measure of wine that was a fourth of a legger . It was also roughly equivalent to a British tierce [159.1 (≈159) liters, 35 Imp. gals.], a measure equal to a third of a butt .
