Choosing the right temperature conversion
Temperature scales do not share the same zero point, so Celsius and Fahrenheit require both multiplication and an offset. Kelvin uses the same interval size as Celsius but begins at absolute zero.
For weather, a rounded whole degree may be enough. Cooking, laboratory, and technical work can require tighter precision and should follow the tolerances of the original source or instrument.
Common uses
- Weather forecasts while traveling
- Oven and food temperatures
- Scientific and engineering calculations
Temperature converters
Use converted values confidently
- Celsius to Fahrenheit: multiply by 9/5, then add 32.
- Kelvin is written without a degree symbol.
- A temperature interval converts differently from an absolute temperature.
