Temperature is how hot or cold something is. Our bodies can feel the difference between something which is hot and something which is cold. To measure temperature more accurately, a thermometer can be used. Thermometers use a temperature scale to record how hot or cold something is. The scale used in most of the world is in degrees Celsius, sometimes called "centigrade". In the USA and some other countries degrees Fahrenheit are more often used while scientists mostly use kelvins to measure temperature because it never goes below zero.
