Step-by-Step Worked Example

Step-by-Step Worked Example

Example 1: Celsius to Fahrenheit

Convert 25°C to Fahrenheit:

Step 1: Use formula → °F = (°C × 9/5) + 32

Step 2: Substitute → °F = (25 × 9/5) + 32 = 45 + 32

Step 3: Result → 25°C = 77°F

Example 2: Fahrenheit to Kelvin

Convert 98°F to Kelvin:

Step 1: K = (°F − 32) × 5/9 + 273.15

Step 2: K = (98 − 32) × 5/9 + 273.15 = 66 × 5/9 + 273.15 ≈ 36.67 + 273.15

Step 3: Result → 98°F ≈ 309.82 K
