Understanding Temperature Scales
Temperature is a physical quantity that expresses hot and cold. It's measured using different scales worldwide, with Celsius, Fahrenheit, and Kelvin being the most common.
Temperature Scales Explained
Celsius (°C)
Used in most countries worldwide
- Freezing point of water: 0°C
- Boiling point of water: 100°C
- Room temperature: ~20-25°C
Fahrenheit (°F)
Primarily used in the United States
- Freezing point of water: 32°F
- Boiling point of water: 212°F
- Room temperature: ~68-77°F
Kelvin (K)
Used in scientific applications
- Absolute zero: 0K
- Freezing point of water: 273.15K
- Room temperature: ~293-298K

Conversion Formulas
- Celsius to Fahrenheit: (°C × 9/5) + 32 = °F
- Fahrenheit to Celsius: (°F - 32) × 5/9 = °C
- Celsius to Kelvin: °C + 273.15 = K
- Kelvin to Celsius: K - 273.15 = °C
- Fahrenheit to Kelvin: (°F - 32) × 5/9 + 273.15 = K
- Kelvin to Fahrenheit: (K - 273.15) × 9/5 + 32 = °F
