Understanding This Calculator
Visualizing Temperature scales

Temperature scales differ based on their zero points and increment size. Water freezes at 0°C (32°F) and boils at 100°C (212°F).
1. Celsius to Fahrenheit
multiply by 1.8 (or 9/5) and add 32.
°F = (°C × 9/5) + 32
Example 1: Convert 20°C to °F
- Formula: (20 × 1.8) + 32
- Result: 68°F
Example 2: Convert 0°C to °F
- Formula: (0 × 1.8) + 32
- Result: 32°F
2. Fahrenheit to Celsius
Subtract 32 and multiply by 0.5556 (or 5/9).
°C = (°F - 32) × 5/9
Example 1: Convert 68°F to °C
- Formula: (68 - 32) × 0.5556
- Result: 20°C
Example 2: Convert 100°F to °C
- Formula: (100 - 32) × 0.5556
- Result: 37.78°C
