Rankine
Rankine (°R) is an absolute temperature scale used primarily in engineering, where 0°R represents absolute zero and each degree Rankine is equivalent to one degree Fahrenheit.
History/Origin
The Rankine scale was introduced by William John Macquorn Rankine in 1859 as an absolute temperature scale based on the Fahrenheit degree, primarily used in the United States for thermodynamic calculations.
Current Use
Today, the Rankine scale is mainly used in certain engineering fields within the United States, especially in thermodynamics and heat transfer calculations, but it is largely replaced by the Kelvin scale in scientific contexts.
Celsius
Celsius (°C) is a unit of temperature measurement where 0°C is the freezing point of water and 100°C is the boiling point at standard atmospheric pressure.
History/Origin
The Celsius scale was developed by Anders Celsius in 1742, originally with 0°C as the boiling point of water and 100°C as the freezing point, later reversed to its current form.
Current Use
Celsius is widely used worldwide for everyday temperature measurements, scientific research, and weather reporting, especially in most countries outside the United States.
