Understanding Fahrenheit and Celsius
Fahrenheit (°F)
Imperial temperature scale
• Developed by Daniel Fahrenheit in 1724
• Water freezes at 32°F, boils at 212°F
• Primarily used in the United States
• Smaller degree increments than Celsius
• Originally based on brine freezing point
Celsius (°C)
Metric temperature scale
• Ideal for scientific measurements
• Perfect for weather reporting worldwide
• Used in cooking in most countries
• Easy to understand water-based scale
Practical Examples
Everyday Use
- • Room temperature (68°F) = 20°C
- • Comfortable outdoor temperature (77°F) = 25°C
- • Hot summer day (86°F) = 30°C
- • Freezing weather (32°F) = 0°C

Conversion Tips
Quick Mental Calculation
For approximate conversions, remember these quick methods:
- Subtract 32, divide by 2, add 10%
- Example: 68°F → (68-32)=36 → 18 + 1.8 = 19.8°C
- 32°F = 0°C (freezing point)
