How to Convert Fahrenheit to Celsius

Mathematical Formula: (F - 32) * 5 / 9 = C Detailed Step-by-Step Conversion for 31°F: Step 1: Subtract 32 from the Fahrenheit value. 31 - 32 = -1 Step 2: Multiply the result by 5. -1 * 5 = -5 Step 3: Divide by 9 to find the final Celsius value. -5 / 9 = -0.5556°C Final Result: 31°F is exactly equal to -0.5556°C.

Mathematical Derivation

°C = (°F − 32) × 5 ÷ 9

= (31 − 32) × 5 ÷ 9

= -1 × 5 ÷ 9

= -5 ÷ 9

= -0.5556°C

Step-by-Step Calculation

Convert 31°F to Celsius step by step:

Step 1: Subtract 32 from the Fahrenheit temperature.
31 − 32 = -1

Step 2: Multiply the result by 5.
-1 × 5 = -5

Step 3: Divide the result by 9.
-5 ÷ 9 = -0.5556

31°F = -0.5556°C
