Complete Temperature Guide
Temperature conversion between Celsius and Fahrenheit is essential in science, cooking, weather forecasting, and international communication. Understanding both scales helps you work with temperature data from different regions and applications.
Understanding Celsius Scale
The Celsius scale, developed by Anders Celsius in 1742, is based on the freezing point (0°C) and boiling point (100°C) of water at standard atmospheric pressure. It's used worldwide in science and most countries for daily weather reporting.
- Water freezes at 0°C
- Water boils at 100°C
- Human body temperature: ~37°C
- Room temperature: ~20-22°C
Understanding Fahrenheit Scale
The Fahrenheit scale, created by Daniel Gabriel Fahrenheit in 1724, sets water's freezing point at 32°F and boiling point at 212°F. It's primarily used in the United States, Bahamas, Belize, and the Cayman Islands.
- Water freezes at 32°F
- Water boils at 212°F
- Human body temperature: ~98.6°F
- Room temperature: ~68-72°F
Conversion Tips
Quick mental conversion tricks for everyday use:
- C to F: Double and add 30 (approximate)
- F to C: Subtract 30 and halve (approximate)
- Exact formula C to F: (°C × 9/5) + 32
- Exact formula F to C: (°F - 32) × 5/9
Frequently Asked Questions
What is the difference between Celsius and Fahrenheit?
Celsius and Fahrenheit are two different temperature scales. Celsius (°C) is based on the freezing point of water at 0°C and boiling point at 100°C. Fahrenheit (°F) uses 32°F for water's freezing point and 212°F for its boiling point.
