Conversion
To convert °F HDD to °C HDD: °C HDD = (5/9) x (°F HDD)
To convert °C HDD to °F HDD: °F HDD = (9/5) x (°C HDD)
Note that, because HDD are relative to a base temperature (as opposed to being relative to zero), it is incorrect to add or subtract 32 when converting degree days from Celsius to Fahrenheit or vice versa.
