Subtract 30 from the Fahrenheit number and cut it in half. Example: 80°F - 30 = 50; 50 ÷ 2 = 25°C (Actual is 26.6°C). Common Reference Points

If you don't have a calculator handy, these are the primary formulas used to move between scales: If you don't have a calculator handy, these
The Kelvin scale is the standard for the physical sciences. It begins at (0 K), the theoretical point where all molecular motion stops. Unlike Fahrenheit and Celsius, Kelvin does not use "degrees"—it is an absolute scale. Water freezes at 273.15 K and boils at 373.15 K . Key Formulas for Temperature Conversion
Temperature conversion isn't just about the weather. In , pilots must convert temperatures to calculate air density and engine performance. In medicine , dosages and storage requirements for vaccines are often strictly measured in Celsius. In culinary arts , baking a delicate souffle at 180°C instead of 180°F would result in a very different (and likely burnt) outcome.
