Temperature conversion allows you to change a temperature value from one measurement system to another. The most common temperature scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K). Each scale uses a different starting point and measurement system.
Temperature Conversion Formulas
Use these formulas to convert between the most common temperature units:
Celsius to Fahrenheit:
°F = (°C × 9/5) + 32
Fahrenheit to Celsius:
°C = (°F − 32) × 5/9
Celsius to Kelvin:
K = °C + 273.15
- °C = Temperature in Celsius
- °F = Temperature in Fahrenheit
- K = Temperature in Kelvin
Temperature Conversion Example
To convert 25°C to Fahrenheit:
(25 × 9/5) + 32 = 77°F
Therefore, 25 degrees Celsius is equal to 77 degrees Fahrenheit.
Common Temperature Reference Points
- 0°C = 32°F = 273.15K (Freezing point of water)
- 100°C = 212°F = 373.15K (Boiling point of water)
- -273.15°C = 0K (Absolute zero)
