Temperature is a physical quantity that expresses hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. The most commonly used scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K).
Major Temperature Scales
Celsius (°C)
- Water freezes at 0°C
- Water boils at 100°C
- Room temperature is ~20-25°C
- Body temperature is ~37°C
- Used in most countries worldwide
Fahrenheit (°F)
- Water freezes at 32°F
- Water boils at 212°F
- Room temperature is ~68-77°F
- Body temperature is ~98.6°F
- Used primarily in the United States
Kelvin (K)
- Absolute zero is 0K (-273.15°C)
- Water freezes at 273.15K
- Water boils at 373.15K
- No degree symbol used
- Used in scientific applications
Conversion Formulas
| From | To | Formula | Example |
|---|---|---|---|
| Celsius | Fahrenheit | °F = (°C × 9/5) + 32 | 20°C = 68°F |
| Fahrenheit | Celsius | °C = (°F - 32) × 5/9 | 68°F = 20°C |
| Celsius | Kelvin | K = °C + 273.15 | 20°C = 293.15K |
| Kelvin | Celsius | °C = K - 273.15 | 293.15K = 20°C |
| Fahrenheit | Kelvin | K = (°F - 32) × 5/9 + 273.15 | 68°F = 293.15K |
| Kelvin | Fahrenheit | °F = (K - 273.15) × 9/5 + 32 | 293.15K = 68°F |
