[gr]Grain
Definisjon
- A grain is a unit of measurement of mass that is nominally based upon the mass of a single seed of a cereal. The grain is the only unit of mass measure common to the three traditional English mass and weight systems; the obsolete Tower grain was, by definition, exactly /64 of a troy grain. Since 1958, the grain or troy grain measure has been defined in terms of units of mass in the International System of Units as precisely 64.79891 milligrams. Thus, $1 gram \\approx 15.4323584 grains$. There are precisely 7,000 grains per avoirdupois pound in the imperial and U.S. customary units, and 5,760 grains in the Troy pound.
