Arrange the steps for converting a Fahrenheit temperature to Celsius.

### The order 1. **Record the starting temperature in Fahrenheit.** The starting scale determines which conversion formula to use. 2. **Subtract 32 from the Fahrenheit value.** This adjusts for the different zero points of the scales. 3. **Multiply the difference by $5/9$.** This rescales the temperature interval. 4. **Report the result in Celsius.** The calculation has now changed the temperature scale. ### The concept The full relation is $C=(F-32)\times5/9$. Reversing the steps or using the reciprocal factor gives the wrong scale conversion. ### Terms - **Fahrenheit (°F)**: the starting temperature scale in this conversion. - **Celsius (°C)**: the target temperature scale. ### Remember Subtract 32 before multiplying by $5/9$.
