Kelvin

Definition

The kelvin (K) is the SI base unit of thermodynamic temperature and is also used for temperature intervals. When measuring temperature differences, one kelvin equals one degree Celsius, making it the standard unit for temperature interval measurements in scientific and engineering applications.

History/Origin

Named after Lord Kelvin (William Thomson), the kelvin was established as the SI base unit for temperature in 1967. It was designed to provide an absolute temperature scale where zero represents absolute zero, and temperature intervals are measured in the same units as the temperature scale itself.

Current Use

Widely used in scientific research, engineering, and industrial applications for measuring temperature differences and intervals. It is the standard unit for temperature interval measurements in thermodynamics, heat transfer analysis, and temperature control systems.

Degree Celsius

°C

Definition

The degree Celsius (°C) is a unit of temperature interval equal to one kelvin. When measuring temperature differences rather than absolute temperatures, one degree Celsius equals one kelvin, making it equivalent for interval measurements in the Celsius temperature scale.

History/Origin

Named after Anders Celsius, the degree Celsius was originally defined as 1/100 of the temperature difference between the freezing and boiling points of water. For temperature intervals, it maintains the same scale as the kelvin, providing a practical unit for everyday temperature difference measurements.

Current Use

Commonly used in everyday applications, weather reporting, and engineering for measuring temperature differences. It is widely used in HVAC systems, industrial processes, and scientific research where temperature intervals are measured in Celsius scale.
