Play math three times at centigrade.
These three numbers should be 273, because 273 is the standard temperature scale of Celsius.

The standard temperature scale is in the19th century, and it is still generally believed in physics that heat is an immortal substance.

1848, william thomson founded the thermodynamic temperature scale according to the theories of Guy Lussac, Cano and clapper Long.

And pointed out: "The characteristic of this temperature scale is that it does not depend on any special physical properties at all." This is the standard temperature scale in the sense of modern science.

Centigrade was put forward by Swedish astronomer Anders Centigrade in 1742, and has been continuously improved since then. The meaning of degree Celsius means that the temperature of pure ice-water mixture is 0 degree Celsius and the boiling point of water is 1 00 degree Celsius at1standard atmospheric pressure.

Centigrade scale (c) unit of temperature measurement, signed? C indicates that it is one of the most widely used temperature scales in the world. Celsius is now part of the International System of Units (SI).

T (k) = t (c)+273. 15, where t is the absolute temperature scale.
