Scale information

Rankine

The Rankine scale is a thermodynamic (absolute) scale named after the Scottish engineer and physicist William John Macquom Rankine (1820-1872), who proposed it in 1859. The freezing point of water is set at 491.67°R and the boiling point at 671.64102°R.

Celsius

The Celsius scale (also known as centigrade) is a temperature scale named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar scale. From 1744 until 1954 0°C was defined as the freezing point of water and 100°C as the boiling point (at standard atmospheric pressure).
