Temperature Converter

Celsius, Fahrenheit and Kelvin conversions for weather, cooking and school science — not a fever protocol.

How it's calculated

°F = °C × 9/5 + 32; K = °C + 273.15; inverses as usual.

About this calculator

News weather in °C and a fever discussion in °F should not share a number without conversion. This tool does the linear transforms.

Clinical fever thresholds belong to a doctor. Cooking oil smoke points need recipe context, not only a converted integer.

Frequently Asked Questions

Everything is normalised to Celsius, then to the target. C→F: ×9/5 + 32. C→K: +273.15. Inverse for F and K. Offset means you cannot simply multiply Fahrenheit by a length-style factor.
Celsius, Fahrenheit, Kelvin only (handler UNITS).
0 K = −273.15 °C. Values below 0 K are physically invalid; the engine may still arithmetic unless it validates.
Same scales. 200 °C oven ≠ 200 °F. Convert explicitly.
The result is still the Kelvin number. Naming is display.
Not offered.
= 37 °C exactly in the usual conversion (37 × 9/5 + 32 = 98.6). Clinical thermometers still vary.
Convert here; do not add 32 to a °C value without ×9/5.
Yes (−40 is the coincidence). The formula still holds.
Gas mark is not a thermodynamic scale in this tool.
