Conversion tables


Fahrenheit and 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.
