Common Temperature Units
Celsius (°C)
Celsius is the most widely used temperature scale worldwide. It is commonly used for weather forecasts, scientific measurements, and everyday temperature readings.
Key points:
- Water freezes at 0°C
- Water boils at 100°C
- Standard scale in most countries
The Celsius scale was developed by Swedish astronomer Anders Celsius and is part of the metric system.
Fahrenheit (°F)
Fahrenheit is primarily used in the United States and a few other regions.
Key points:
- Water freezes at 32°F
- Water boils at 212°F
- Commonly used in weather reports in the U.S.
Many travelers use temperature converters to understand Fahrenheit temperatures when visiting countries that use Celsius.
Kelvin (K)
Kelvin is the standard temperature unit used in science and engineering.
Key points:
- Absolute zero is 0 K
- Water freezes at 273.15 K
- Water boils at 373.15 K
Kelvin is widely used in thermodynamics, chemistry, and physics because it starts from absolute zero, the theoretical point where molecular motion stops.
Temperature Conversion Formulas
A temperature converter uses standard scientific formulas to convert between units.
Celsius to Fahrenheit
Formula:
F = (C × 9/5) + 32
Example:
25°C = 77°F
Fahrenheit to Celsius
Formula:
C = (F − 32) × 5/9
Example:
77°F = 25°C
Celsius to Kelvin
Formula:
K = C + 273.15
Example:
25°C = 298.15 K
Kelvin to Celsius
Formula:
C = K − 273.15
Example:
298.15 K = 25°C
Fahrenheit to Kelvin
Formula:
K = (F − 32) × 5/9 + 273.15
Example:
77°F = 298.15 K
Kelvin to Fahrenheit
Formula:
F = (K − 273.15) × 9/5 + 32
Example:
298.15 K = 77°F
