rankine

Thân thiện

A scientist records the temperature in rankine on a digital display.

Definition

Noun: A unit of absolute temperature in the Rankine scale (°R), where zero is absolute zero (the point at which all molecular motion ceases). One degree Rankine is equal in magnitude to one degree Fahrenheit, but the Rankine scale starts at absolute zero, whereas the Fahrenheit scale starts at a different point. Therefore, 0 °R = -459.67 °F.

Usage

The word "rankine" (often capitalized as "Rankine" when referring to the scale) is used specifically in scientific and engineering contexts, particularly in thermodynamics within the U.S. customary system, to express absolute temperature.

Examples

• The engine's exhaust gas was measured at 1250 Rankine.
• To convert from Fahrenheit to Rankine, add 459.67.
• Absolute zero is defined as 0 degrees Rankine.

Advanced Usage

• Rankine scale: The full name of the temperature scale on which the unit is based. It is an absolute thermodynamic temperature scale.
  • Example: The Rankine scale is the Fahrenheit equivalent of the Kelvin scale.

Variants and Related Words

• Rankine (adj): Pertaining to the Rankine scale or William Rankine, the Scottish engineer and physicist for whom it is named.
  • Example: The Rankine cycle is a model used to predict the performance of steam engines.

Synonyms

• °R: The symbol for the Rankine unit.
• degree Rankine: The full, formal name of the unit.

Notes on Different Meanings

The word "rankine" functions almost exclusively as a unit of measurement. It does not have other common meanings in general English. Its use is highly specialized.
