What is the Temperature Converter?
The Temperature Converter is an online tool that convert between Celsius, Fahrenheit, Kelvin, and Rankine instantly.
What formula does the Temperature Converter use?
This calculator uses the rule: Convert via Kelvin: K = °C + 273.15. Enter your values in the tool above to apply it to your numbers.
How does the Temperature Converter work?
Temperature uses offset formulas (not simple ratios). We convert through Kelvin: °F = (°C × 9/5) + 32, K = °C + 273.15.
Formula Used
The equation below is what this calculator applies. Variable definitions follow when symbols are used.
