Rankine
The Rankine scale is an absolute temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. Similar to the Kelvin scale, the Rankine scale starts at absolute zero, with each degree Rankine equal to one degree Fahrenheit. This scale is primarily used in thermodynamics and engineering, particularly in the United States. The freezing point of water on the Rankine scale is 491.67 °R, and the boiling point is 671.67 °R.
Celsius
Celsius is a unit of temperature measurement that is part of the metric system. It is named after the Swedish astronomer Anders Celsius, who developed the scale. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees under standard atmospheric pressure. It is widely used in scientific and everyday contexts around the world.
