Temperature is a physical quantity expressing hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. The most commonly used scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Celsius and Fahrenheit are relative scales, while Kelvin is an absolute scale. The Kelvin scale is widely used in scientific applications because it starts at absolute zero, the lowest possible temperature.
