HECTO-

(Redirected from Hecto)

'hecto-' (symbol 'h') is a SI prefix in the SI system of units denoting a factor of 10² (100).
Adopted in 1795, it comes from the Greek ''hekaton'', meaning ''hundred''.
It is rarely used, except for certain specific applications:

★ hectare, 100 ares, or 10,000 square metres, a very common measure of land area.

★ hectopascal, in meteorology, for atmospheric pressure, the modern equivalent of the traditional millibar.

★ hectolitre, in agriculture, for liquids (notably wine and milk) and bulk commodities (''e.g.'' grain).

★ hectogram, in agronomy, for quantities of animal feed (hectogram/animal) and for measures of agricultural productivity (hectogram/hectare); also used in Italy, abbreviated as ''etto'', for retail sale of cold cuts and meat.

★ hectometre, in radio astronomy, occasionally used to indicate a radio band by wavelength
