Celsius (°C)
Definition
Celsius (°C) is a metric temperature scale where 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure.
History
The Celsius scale was proposed in 1742 by Anders Celsius, a Swedish astronomer. His original scale was inverted (0° for boiling, 100° for freezing), and was later reversed by Carl Linnaeus or Daniel Ekström.
Current use
Celsius is the most widely used temperature scale in the world, standard in most countries for weather forecasts, cooking, scientific research, and everyday temperature measurements. Only the US, Liberia, and the Cayman Islands primarily use Fahrenheit.
Rankine (°R)
Definition
Rankine (°R) is an absolute temperature scale where 0°R equals absolute zero (−459.67°F). Each Rankine degree equals one degree Fahrenheit.
History
The Rankine scale was proposed in 1859 by William John Macquorn Rankine, a Scottish physicist and engineer. It was designed as the Fahrenheit-based equivalent of the Kelvin scale for use in thermodynamic engineering.
Current use
Rankine is used primarily in American engineering and thermodynamics, particularly in the aerospace and HVAC industries. Some US engineering textbooks and thermodynamic tables reference Rankine temperatures.
