🧠 How the Temperature Conversion Formula Works

To convert from Fahrenheit (°F) to Celsius (°C):

Use the formula: °C = (°F − 32) × 5⁄9

To convert from Celsius (°C) to Fahrenheit (°F):

Use the formula: °F = (°C × 9⁄5) + 32

🌡️ Step-by-Step Example 1: Convert 77°F to Celsius

1. Subtract 32 from 77: 77 − 32 = 45

2. Multiply 45 by 5/9: 45 × 5⁄9 = 25

✅ So, 77°F = 25°C

🔥 Step-by-Step Example 2: Convert 30°C to Fahrenheit

1. Multiply 30 by 9/5: 30 × 9⁄5 = 54

2. Add 32 to 54: 54 + 32 = 86

✅ So, 30°C = 86°F
