Temperature is measured in degree ___________ .

Hint: Recall that temperature is defined as the measure of hotness or coldness of a body. It is a quantity that is used to determine the direction of the flow of heat in a body. As it is known that the heat flows from a higher temperature body to a lower temperature body.

Complete step by step solution:
Temperature is measured by using a device known as a thermometer. The units that are used to measure temperature are Kelvin, Celsius and Fahrenheit. But the most commonly used units are Celsius. It is also known as Centigrade scale. It is denoted by using the symbol $^ \circ C$. These are all units of temperature. These units are inter convertible and can be changed from one unit to another. Almost all the countries use Celsius scale, but the U.S. is an exception as it uses Fahrenheit scale.
Temperature of a body is measured in degree Celsius/Fahrenheit.

Note: The most commonly used unit to measure temperature is degree Celsius. This is because it is a scale in which zero degree represents the freezing point of water known as lower fixed point and 100 degree represents the boiling point of water known as upper fixed point. The region between these two temperatures is divided into 100 equal parts so that each part is equal to one degree Celsius. It is the mean barometric pressure at the sea level. Also its measurement and readings are considered to be precise and accurate. Also the Celsius scale is convenient to use.
