the abstract; the number represented by 1. The term is used in

which the kind of thing is expressed; a unit of measure or value; as
1 foot, 1 dollar, 1 pound, and the like.

– Physical unit, a value or magnitude conventionally adopted as a
unit or standard in physical measurements. The various physical units

a unit of measure; a thermal unit (see under Thermal). Water is the
substance generally employed, the unit being one gram or one pound,
and the temperature interval one degree of the Centigrade or
Fahrenheit scale. When referred to the gram, it is called the gram
degree. The British unit of heat, or thermal unit, used by engineers
in England and in the United States, is the quantity of heat
necessary to raise one pound of pure water at and near its
temperature of greatest density (39.1Âş Fahr.) through one degree of
the Fahrenheit scale. Rankine.
