- cordel [2]
- a unit of area equal to one square cordel: about 1792 square meters (2143
square yards or 0.433 acre) in Mexico and the
southwestern U.S. or about 414.2 square meters (495.4 square yards).
- coulomb (C)
- the SI unit of electric charge. One coulomb is the
amount of charge accumulated in one second by a current of one ampere.
Electricity is actually a flow of charged particles, such as electrons, protons,
or ions. The charge on one of these particles is a whole-number multiple of
the charge e on a single electron, and one
coulomb represents a charge of approximately 6.241 506 x 1018 e.
The coulomb is named for a French physicist, Charles-Augustin de Coulomb (1736-1806),
who was the first to measure accurately the forces exerted between electric
charges.
- count (ct) [1]
- a unit of quantity equal to 1. This unit is used in commerce to specify
that the quantity stated represents a reliable count. For example, a carton
marked "oranges 24 ct" contains exactly 24 oranges.
- count (ct) [2]
- a traditional unit measuring the texture of a fabric, equal to the number
of threads per inch. A 100 count fabric has
39.37 threads per centimeter.
- count (ct) [3]
- an informal unit of volume in bartending, equal to 0.5 fluid ounce (14.8
milliliters). Bartenders usually fit bottles with pourers designed to restrict
the flow to 0.5 fluid ounce per second. They can then measure a quantity of
liquid by counting, "one thousand one, one thousand two, ..." while pouring.
This is much faster than using a measuring glass, and just about as accurate.
- count (ct) [4]
- a measure of size used in the U.S. for shrimp and similar items described
by the number of items per pound. Thus "50 count" shrimp weigh an average
of 1/50 pound each.
