Understanding Temperature Conversion
Common Temperature Scales
There are three main temperature scales used worldwide:
- Celsius (°C): The most widely used scale internationally. Water freezes at 0°C and boils at 100°C.
- Fahrenheit (°F): Common in the United States. Water freezes at 32°F and boils at 212°F.
- Kelvin (K): The scientific standard, used in physics and chemistry. 0K is absolute zero (-273.15°C).
