How to Convert Fahrenheit to Celsius

Mathematical Formula: (F - 32) * 5 / 9 = C Detailed Step-by-Step Conversion for 100°F: Step 1: Subtract 32 from the Fahrenheit value. 100 - 32 = 68 Step 2: Multiply the result by 5. 68 * 5 = 340 Step 3: Divide by 9 to find the final Celsius value. 340 / 9 = 37.7778°C Final Result: 100°F is exactly equal to 37.7778°C.

Mathematical Derivation

°C = (°F − 32) × 5 ÷ 9

= (100 − 32) × 5 ÷ 9

= 68 × 5 ÷ 9

= 340 ÷ 9

= 37.7778°C

Step-by-Step Calculation

Convert 100°F to Celsius step by step:

Step 1: Subtract 32 from the Fahrenheit temperature.
100 − 32 = 68

Step 2: Multiply the result by 5.
68 × 5 = 340

Step 3: Divide the result by 9.
340 ÷ 9 = 37.7778

100°F = 37.7778°C
