Measurement is defined as a comparison of a physical quantity to a given standard unit. It is the determination of the size or magnitude of something. Measurement provide us with a means of describing various phenomenon in quantitative terms. It can also be considered as the process by which one can convert physical parameters to meaningful numbers.

Temperature is the physical property of an object that measures the degree of hotness or coldness of an object. It is commonly measured in degree Celsius or degree Fahrenheit.
