fahrenheit to celsius formula
What is the formula for Fahrenheit to Celsius?
The formula to convert Fahrenheit to Celsius is: Celsius = (Fahrenheit - 32) × 5/9 (or divide by 1.8). For instance, to convert 100°F to Celsius, subtract 32 to get 68, then multiply by 5 and divide by 9, resulting in 37.78°C. This formula is vital for engineering Thermodynamics, climate reports, weather forecasts, and chemical formulas.
