Informational only; verify critical results independently.
How to use
- Enter the temperature you have (oven, weather, fever, science lab).
- Select whether that number is °C, °F, or K.
- Read the converted values in the other scales side by side.
- Use Kelvin when working with thermodynamics or scientific offsets from absolute zero.
- Double-check oven settings: many recipes use °F while ovens elsewhere use °C.
- Copy one line or note rounded values for reporting.
Examples
- 100 °C boiling water at sea level → °F
- 32 °F freezing → °C
- 0 K to °C (absolute zero reference)
- 180 °C fan oven to °F for a US recipe card
- 37.5 °C body temp to °F
- Room temperature 20 °C to °F for HVAC comparison
FAQ
- Celsius and Fahrenheit formulas?
- °F = °C × 9/5 + 32; °C = (°F − 32) × 5/9. The scales cross at −40°.
- Kelvin conversion?
- K = °C + 273.15. Kelvin has no degree symbol in SI style.
- Why can’t I convert “twice as hot”?
- Temperature ratios aren’t meaningful on °C/°F; use Kelvin for ratios in physics.
- Does this account for altitude when baking?
- No—only unit conversion. Baking adjustments for altitude are separate.
- Negative Fahrenheit to Celsius?
- Yes. Very cold weather (e.g. −40 °F) converts correctly.
- Are calculations private?
- Yes—they run in your browser.
