Temperature is a measure of the hotness or the coldness of an object.
Temperature is an intensive property and does not depend on the amount of substance.
Temperatures are commonly measured using a thermometer calibrated using the Celsius temperature scale in degrees Centigrade (°C).
The kelvin temperature scale used by scientists (developed by Lord Kelvin) has as its zero point the lowest possible temperature (0 K = –273.15 °C).
Conversion between the centigrade and kelvin temperature scale requires addition or subtraction of 273 (for many purposes the exact conversion is not necessary).
T/K = T/°C + 273
(read the forward slash as in)
T/°C = T/K - 273
The size of a kelvin and a degree centigrade are the same.
Therefore differences in kelvin temperatures are equal to the corresponding difference in temperatures in centigrade.

The temperature of a cup of water and a litre of water can be the same.
Temperatures are commonly measured using a thermometer calibrated using the Celsius temperature scale in degrees Centigrade (°C).
0 °C was set arbitrarily to be about the temperature where water freezes.
