About Temperature Converter
Convert between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur with live results as you type. Water freezes at 0 °C (32 °F, 273.15 K) and boils at 100 °C (212 °F, 373.15 K)—use those anchors to sanity-check homework, recipes, and weather data.
How to Use Temperature Converter
Choose the scale you are converting from (for example Celsius). Enter the temperature value in the input field. Select the target scale (for example Fahrenheit). Copy the converted value or download it for lab notes.
When to Use Temperature Converter
Cooking: Translate oven settings when a recipe lists °F but your appliance shows °C. Travel: Interpret forecasts and thermostat labels in countries that use a different scale. Science: Move between Celsius and Kelvin for thermodynamics problems where absolute zero matters. Medicine: Convert body temperature readings between °C and °F for patient records.

Frequently asked questions
What is the formula for Celsius to Fahrenheit?
Multiply by 9/5 and add 32: °F = (°C × 9/5) + 32.
When should I use Kelvin?
Kelvin is an absolute scale starting at absolute zero. Use it in physics and chemistry when relative temperature differences must align with energy calculations.
Are results exact for engineering sign-off?
They follow standard conversion factors and are fine for reference. Certified instruments and regulated workflows need official standards and documented uncertainty.
