Conversion Formula
$$T_{°C} = (T_{°F} - 32) \times \frac{5}{9}$$
Subtract 32 from Fahrenheit and multiply by 5/9 to get Celsius.

°F to °C in Engineering
Temperature conversions are fundamental across all engineering disciplines. Celsius and Fahrenheit are used for everyday measurements, while Kelvin is required for thermodynamic calculations and Rankine for US customary thermodynamic systems.
Degree Fahrenheit: US customary temperature scale. Water freezes at 32°F and boils at 212°F. Standard in US HVAC and weather.
Degree Celsius: International standard temperature scale. Water freezes at 0°C and boils at 100°C under standard conditions.
