About (symbol:

Definition: Rankine (symbol: °R) is an absolute temperature scale using Fahrenheit-sized degrees, with 0°R at absolute zero (-459.67°F).

History: Named after Scottish engineer William Rankine in 1859. Combines absolute zero concept with Fahrenheit degree intervals.

Current Use: Used primarily in engineering applications in the United States, particularly in thermodynamics and heat transfer calculations.

Examples: Engineering calculations, thermodynamics, power plant operations, HVAC systems

About (symbol:

Definition: Celsius (symbol: °C) is a temperature scale where water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Originally called centigrade.

History: Developed by Swedish astronomer Anders Celsius in 1742, originally with 0° as boiling point and 100° as freezing point. The scale was inverted after his death to the current form.

Current Use: Standard temperature scale used worldwide for weather, cooking, medical measurements, and scientific applications. Official scale in most countries except the United States.

Examples: Weather: -10°C to 40°C, cooking: 180°C oven, fever: 39°C, refrigerator: 4°C
