About Temperature Conversions

Temperature is a physical quantity that expresses hot and cold. It is measured with a thermometer calibrated in one or more temperature scales.

The Kelvin (K) is the SI base unit of temperature. Other common units include Celsius (°C) and Fahrenheit (°F).

The Celsius scale is used in most countries for everyday temperature measurement, while the Fahrenheit scale is primarily used in the United States.
The Kelvin scale is used in scientific contexts, with 0 K representing absolute zero, the theoretical absence of all thermal energy.

Temperature conversion is essential in weather forecasting, cooking, scientific research, and many industrial processes.

Temperature Units Explained

Celsius (°C)

The Celsius scale is a temperature scale used by the International System of Units (SI). It was previously known as the centigrade scale. 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure.

Fahrenheit (°F)

The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. On this scale, the freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure.

Kelvin (K)

The Kelvin is the SI base unit of temperature. It is defined by setting the fixed numerical value of the Boltzmann constant to 1.380649×10^−23 J/K. The Kelvin scale is an absolute thermodynamic temperature scale, with 0 K representing absolute zero.
