es; graduated into a hundred divisions or equal parts. Spesifically: of or pertaining the centigrade thermometer; as, 10° centigrade (or 10° C.). Centigrade thermometer, a thermometer having the zero or 0 at the point indicating the freezing state of water, and the distance between that and the point indicating the boi…

e ginning, or zero point, in the scale of absolute temperature. It is equivalent to -273º centigrade or -459.4º Fahrenheit.

that pressure under which the barometer stands at 760 millimeters, at a temperature of 0º Centigrade, at the level of the sea, and in the latitude of Paris. Sir W. Thomson.

quires to raise the temperature of one kilogram (sometimes, one gram) of water one degree centigrade, or from 0Foot pound.

called from Anders Celsius, a Swedish astronomer, who invented it. It is the same as the centigrade thermometer or scale.

d by Dr. Mayer of Heilbronn. Its value was found by Joule to be 1390 foot pounds upon the Centigrade, or 772 foot pounds upon the Fahrenheit, thermometric scale, whence it is often called Joule's equivalent, and represented by the symbol J. This is equal to 424 kilogram meters (Centigrade scale). A more recent determin…

freeze; -- applied particularly to water, whose freezing point is at 32º Fahr., and at 0º Centigrade.

he amount of heat necessary to raise the temperature of one gram of pure water one degree centigrade. -- Gram equivalent (Electrolysis), that quantity of the metal which will replace one gram of hydrogen.

itially at a certain standard temperature. The temperature usually employed is that of 0º Centigrade, or 32º Fahrenheit.

temperature at which a solid substance melts or fuses; as, the melting point of ice is 0º Centigrade or 32º Fahr., that of urea is 132º Centigrade. -- Melting pot, a vessel in which anything is melted; a crucible.

essary to raise the temperature of one gram or one pound of water from zero to one degree Centigrade. See Calorie, and under Unit.

yed, 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…

se temperature at which water attains its maximum density. This is about 39º Fahr., or 4º Centigrade; and from that point down to 32º Fahr., or 0º Centigrade, or the freezing point, it expands.
