Kelvin

K

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 Fahrenheit

°F

Definition

The degree Fahrenheit (°F) is a unit of temperature interval equal to 5/9 of a kelvin. When measuring temperature differences, one degree Fahrenheit represents a smaller temperature change than one degree Celsius or one kelvin, making it useful for precise temperature interval measurements.

History/Origin

Named after Daniel Gabriel Fahrenheit, the degree Fahrenheit was originally defined as 1/180 of the temperature difference between the freezing and boiling points of water. For temperature intervals, it provides a finer resolution than Celsius, with 1.8°F equal to 1°C.

Current Use

Widely used in the United States for measuring temperature differences in weather, HVAC systems, and industrial processes. It is commonly used in temperature control systems where finer resolution is needed for temperature interval measurements.
