What is the si unit of temperature?
The SI (International System of Units) unit of temperature is the Kelvin, abbreviated as "K." The Kelvin scale is an absolute temperature scale, and it is commonly used in scientific and engineering contexts, especially in physics and chemistry. Unlike the Celsius (°C) and Fahrenheit (°F) scales, which have arbitrary zero points (the freezing point of water for Celsius and a mixture of ice and salt for Fahrenheit), the Kelvin scale starts from absolute zero, which is the lowest possible temperature where molecular motion ceases.
The Kelvin scale is related to the Celsius scale by the following equation:
Kelvin (K) = Celsius (°C) + 273.15
In the Kelvin scale, absolute zero is 0 K, and temperatures are measured in kelvins above absolute zero. This makes Kelvin a useful scale for scientific calculations, particularly in fields like thermodynamics, where temperature is a critical parameter.
