FAHRENHEIT/CENTIGRADE (CELSIUS) TEMPERATURE CONVERSION
To convert degrees Fahrenheit (°F) into degrees Centigrade (°C, or Celsius), subtract 32, then multiply by 5, then divide by 9. To convert degrees C into degrees F, multiply by 9, then divide by 5, then add 32. For extrapolation into “subzero” (below 0°F) range, be aware that 1 Fahrenheit degree represents the temperature change of 5/9 of a Centigrade degree, or 1 Centigrade degree represents 1.8 times the temperature change of a Fahrenheit degree. For example, to obtain the Centigrade number equivalent to 0°F, subtract 32 from 0° (which yields −32), then multiply by 5/9, which yields −17.8 Centigrade. However, recall that when most people use the phrase 17 below, they are referring to below 0 on the Fahrenheit scale.
