##### Temperature - Conversion

The temperature is one of the fundamental metric in the International System of Units (SI), which is a physical property of matter. The basic unit of temperature in the SI is the Kelvin (symbol "K"). Generally, temperature is measured with thermometers, which may be calibrated to a variety of temperature scales. For everyday applications, it usually uses the unit of Celsius scale. Temperature is really important, especially in all fields of natural science.
