ToolAtlasThe pair people type into search. Same arithmetic as a textbook: multiply and add. Other unit families live on the general converter.
A US forecast in Fahrenheit, a European recipe in Celsius, a group chat arguing whether 20 °C is “jacket weather.” This URL exists because that pair is what people type. The math is linear. We do not pull METAR, and we do not certify a thermometer.
Body temperature, vaccine storage, and lab work have tolerances this page will not claim. If you needed kilometers or fluid ounces, use the unit converter. Kitchen scaling that is really “what is 15% more” belongs on percentage.
Travel and oven cards
US forecasts and oven boxes still print °F. The factor is the same as the general unit converter; this URL exists because people type the pair. It is not a medical thermometer and not a calibrated lab instrument. Oven cavities drift; treat 350 °F → °C as a starting point.
How to use it
- Enter the value and pick the direction.
- Read the other scale. Rounding is ordinary floating point, not a metrology lab.
- For weather clothing, still look out the window.
Honest limits
Not a forecast. Not Kelvin-first science UI. Not medical advice.
