fahrenheit thermometer
Definition
Noun: A Fahrenheit thermometer is a thermometer that uses the Fahrenheit scale for measurement. This means its scale is divided into degrees Fahrenheit (°F), where the freezing point of water is 32°F and the boiling point is 212°F under standard atmospheric pressure.
Usage
The term is used to specify the type of scale on a thermometer, distinguishing it from one using the Celsius or Kelvin scale. - The old recipe called for the syrup to reach 240°F, so I had to use a Fahrenheit thermometer. - In the United States, weather temperatures are typically reported using a Fahrenheit thermometer.
Advanced Usage
- The term can be used in historical or technical contexts to discuss measurement systems.
- Gabriel Fahrenheit's invention of the Fahrenheit thermometer in the early 18th century provided a more precise instrument for its time.
Variants and Related Words

- Celsius thermometer (n): A thermometer calibrated in degrees Celsius.
Synonyms
- Mercury thermometer (when it uses the Fahrenheit scale and contains mercury)
- Temperature gauge (a more general term, but context specifies the scale)
Notes
- The term is a compound noun. The primary word is "thermometer," with "Fahrenheit" acting as an adjective specifying the calibration type. It refers specifically to the instrument's scale, not its physical construction (e.g., liquid-in-glass, digital).
Noun
-
