Temperature conversions are among the most common unit conversions people need to perform. Here's a comprehensive guide to converting between different temperature scales:
Celsius to Fahrenheit
Formula: °F = (°C × 9/5) + 32
Example: 20°C to Fahrenheit
°F = (20 × 9/5) + 32 = 36 + 32 = 68°F
Fahrenheit to Celsius
Formula: °C = (°F - 32) × 5/9
Example: 68°F to Celsius
°C = (68 - 32) × 5/9 = 36 × 5/9 = 20°C
Key Temperature Points
- Water freezes: 0°C / 32°F
- Room temperature: ~20-22°C / ~68-72°F
- Body temperature: 37°C / 98.6°F
- Water boils: 100°C / 212°F
For quick estimates, remember that:
- 0°C is 32°F (freezing point of water)
- 10°C is 50°F (cool)
- 20°C is 68°F (room temperature)
- 30°C is 86°F (warm)
- 40°C is 104°F (hot)
