Temperature Converter
A free temperature converter that instantly converts between Celsius, Fahrenheit, and Kelvin.
How temperature conversion works
Celsius to Fahrenheit: (C × 9/5) + 32. Fahrenheit to Celsius: (F − 32) × 5/9. Celsius to Kelvin: C + 273.15. This converter applies these formulas automatically and instantly.
Why three scales exist
Celsius is used worldwide for everyday temperature, Fahrenheit is standard in the US, and Kelvin is the scientific absolute-temperature scale used in physics and chemistry.
Common Mistakes to Avoid
Forgetting the +32 offset when converting to Fahrenheit
Solution:
Fahrenheit isn't a simple multiple of Celsius — the formula requires both a multiplication and an offset, which this converter applies automatically.
Treating 0°C and 0°F as the same starting point
Solution:
0°C = 32°F, not 0°F — they use different zero points, unlike Celsius and Kelvin which share the same scale spacing.
Confusing Kelvin with Celsius directly
Solution:
Kelvin has no negative values and starts at absolute zero (−273.15°C) — always convert explicitly rather than assuming Kelvin equals Celsius.
