What Is a Temperature Converter?
A Temperature Converter is an online tool that changes a temperature value from one scale to another. It helps users convert Celsius to Fahrenheit, Fahrenheit to Celsius, Celsius to Kelvin, and other supported temperature units.
Temperature scales use different reference points and intervals. Therefore, temperature conversion involves both multiplication and addition or subtraction rather than simply multiplying by a unit factor.
For example, 0°C is equal to 32°F, while 100°C is equal to 212°F. Both values describe the same temperatures using different scales.
Common Temperature Scales
Celsius (°C)
Celsius is widely used around the world for weather reports, everyday temperature measurements, cooking, and education. At standard atmospheric pressure, water freezes at 0°C and boils at 100°C.
Fahrenheit (°F)
Fahrenheit is commonly used for everyday temperature reporting in the United States. At standard atmospheric pressure, water freezes at 32°F and boils at 212°F.
Kelvin (K)
Kelvin is the SI base unit of thermodynamic temperature and is commonly used in scientific calculations. Kelvin starts at absolute zero, the theoretical lowest possible temperature.
| Scale | Symbol | Water Freezing Point | Water Boiling Point |
|---|---|---|---|
| Celsius | °C | 0°C | 100°C |
| Fahrenheit | °F | 32°F | 212°F |
| Kelvin | K | 273.15 K | 373.15 K |
Temperature Conversion Formulas
Temperature conversion formulas account for the different intervals and starting points of each scale.
Celsius to Fahrenheit
Formula: °F = (°C × 9/5) + 32
Example: 25°C × 9/5 + 32 = 77°F.
Fahrenheit to Celsius
Formula: °C = (°F − 32) × 5/9
Example: (68°F − 32) × 5/9 = 20°C.
Celsius to Kelvin
Formula: K = °C + 273.15
Example: 25°C + 273.15 = 298.15 K.
Kelvin to Celsius
Formula: °C = K − 273.15
Example: 300 K − 273.15 = 26.85°C.
Fahrenheit to Kelvin
Formula: K = (°F − 32) × 5/9 + 273.15
Example: 68°F converts to 293.15 K.
Kelvin to Fahrenheit
Formula: °F = (K − 273.15) × 9/5 + 32
Example: 300 K converts to 80.33°F approximately.

What is a Temperature Converter?
A Temperature Converter changes temperature values between scales such as Celsius, Fahrenheit, and Kelvin.
How do I convert Celsius to Fahrenheit?
Multiply the Celsius temperature by 9/5 and then add 32. The formula is °F = (°C × 9/5) + 32.
How do I convert Fahrenheit to Celsius?
Subtract 32 from the Fahrenheit value and multiply the result by 5/9. The formula is °C = (°F − 32) × 5/9.
What is 0°C in Fahrenheit?
0°C is equal to 32°F.
What is 100°C in Fahrenheit?
100°C is equal to 212°F.
What is 25°C in Fahrenheit?
25°C is equal to 77°F.
What is Kelvin?
Kelvin is the SI base unit of thermodynamic temperature. Its zero point is absolute zero.
How do I convert Celsius to Kelvin?
Add 273.15 to the Celsius temperature. The formula is K = °C + 273.15.
Can Celsius temperatures be negative?
Yes. Celsius temperatures below 0°C are negative and indicate temperatures below the Celsius freezing point of water.
Can Kelvin temperatures be negative?
Ordinary thermodynamic temperatures on the Kelvin scale cannot be below 0 K, which represents absolute zero.
At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit have the same numerical value at −40 degrees. Therefore, −40°C = −40°F.
Why are temperature conversion formulas different from length conversion formulas?
Temperature scales have different starting points and intervals. Therefore, conversions require both scaling and offset adjustments.
