Temperature Converter
Convert Celsius, Fahrenheit, and Kelvin instantly. Supports common conversions like C to F and F to C with live updates.
Privacy: calculations run locally in your browser. No inputs are stored or sent to a server.
How it works
Temperature conversion uses both scaling and offset adjustments.
Formulas:
C → F: (°C × 9/5) + 32
F → C: (°F − 32) × 5/9
C → K: °C + 273.15
K → C: K − 273.15
How to interpret results:
- Celsius: used in most countries and weather reports
- Fahrenheit: used mainly in the United States
- Kelvin: used in science and engineering
Use this tool when comparing temperatures across regions or converting scientific values.
Examples
- Weather: Convert °F to °C when traveling internationally.
- Cooking: Convert oven temperatures between systems.
- Science: Convert °C to Kelvin for experiments.
Examples:
- 0°C = 32°F = 273.15 K
- 100°C = 212°F = 373.15 K
- 98.6°F ≈ 37°C (body temperature)
- 300 K ≈ 26.85°C

FAQ
- Why is temperature conversion different?
Unlike other units, temperature includes both scaling and offsets (e.g., +32 or +273.15).
- Can I use negative values?
Yes. Temperatures like −10°C or −40°F are valid and handled correctly.
- Why do results sometimes look rounded?
Some conversions produce long decimals, so values are formatted for readability.
- What is absolute zero?
Absolute zero is 0 K (−273.15°C), the lowest possible temperature.
- Why is −40 the same in C and F?
At −40, both Celsius and Fahrenheit scales intersect.
- Is my data stored?
No. All calculations run locally in your browser.
