- Degree of frost
-
A degree of frost is a non-standard unit of measure for air temperature meaning degrees below melting point (also known as "freezing point") of water (32 degrees Fahrenheit or 0 degrees Celsius). "Degree" in this case can refer to degree Celsius or Fahrenheit.
When based on Celsius, 0 degrees of frost is the same as 0°C, and any other value is simply the negative of the Celsius temperature. When based on Fahrenheit, the conversion is a bit more complicated, as 0 degrees of frost is equal to 32°F. Conversion formulas:
- T [degrees of frost] = 32°F - T [°F]
- T [°F] = 32°F - T (degrees of frost)
Example: 5 degrees of frost equals 32°F - 5°F = 27°F.[1][2]
The term 'degrees of frost' was widely used in Apsley Cherry-Garrard's account of his Antarctic adventures in "The Worst Journey in the World". He recorded 109.5 (Fahrenheit) degrees of frost (-77.5 °F or -60.8 °C).
