When this temperature conversion is useful

  • Comparing weather, thermostat, cooking, appliance, and equipment settings.
  • Reading a lab, classroom, or technical value written in another temperature scale.
  • Checking a Fahrenheit/Celsius value before setting an oven or process target.

Rounding temperature results

  • Whole degrees are usually enough for weather and comfort settings.
  • Use one decimal place or more when a recipe, lab, or calibration range is narrow.
  • Remember that temperature conversions use offsets, so rounding before the offset can change the result.

Temperature conversion mistakes

  • Using a simple multiplier instead of the Celsius/Fahrenheit offset formula.
  • Confusing a temperature value with a temperature change.
  • Forgetting that Kelvin is an absolute scale.
