Temperature Conversion Formulas
Celsius to Fahrenheit
Example: 25°C = (25 × 9/5) + 32 = 77°F
Fahrenheit to Celsius
Example: 98.6°F = (98.6 - 32) × 5/9 = 37°C
Celsius to Kelvin
Example: 0°C = 0 + 273.15 = 273.15 K
Kelvin to Celsius
Example: 300 K = 300 - 273.15 = 26.85°C
Fahrenheit to Kelvin
Example: 32°F = (32 - 32) × 5/9 + 273.15 = 273.15 K
Kelvin to Fahrenheit
Example: 373.15 K = (373.15 - 273.15) × 9/5 + 32 = 212°F

Frequently Asked Questions
How to convert Celsius to Fahrenheit?
Multiply the Celsius temperature by 9/5 (or 1.8) and add 32. Formula: °F = °C × 9/5 + 32
What is the difference between Celsius and Kelvin?
Kelvin is an absolute temperature scale starting at absolute zero. To convert: K = °C + 273.15. The difference is always 273.15 degrees.
Why does the US use Fahrenheit?
The US adopted Fahrenheit before the metric system became standard. Most other countries use Celsius, which is part of the metric system.
