Snow and avalanche observations are based on the Celsius temperature scale. A comfortable room temperature is slightly over +20 degrees C. Snow melts at 0 degrees C and is cold enough to squeak at –20 degrees C. The formulas for converting from Celsius (C) to Fahrenheit (F) are: F = 9/5 C + 32 and C = 5/9 (F – 32). Convert –20 degrees C to degrees F.
