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
