Temperature Converter

Temperature Converter

Convert between Fahrenheit, Celsius, and Kelvin instantly. Whether you are following a recipe from another country, checking weather forecasts while traveling, or working on a chemistry problem that requires Kelvin, this converter handles the math accurately so you do not have to.

How Temperature Conversion Is Calculated

Unlike most unit conversions that use simple multiplication, temperature requires offset formulas. Fahrenheit to Celsius: C = (F - 32) x 5/9. Celsius to Fahrenheit: F = C x 9/5 + 32. Celsius to Kelvin: K = C + 273.15. The converter first translates any input to Celsius as an intermediate step, then converts to the target unit.

Example

Key Factors in Temperature Conversions

• The -40 crossover — Fahrenheit and Celsius are equal at -40, a useful fact for quick mental checks
• Kelvin for science — Kelvin starts at absolute zero (0 K = -273.15 °C) and is used in physics, chemistry, and engineering
• Body temperature — normal body temp is 98.6 °F / 37 °C, a common reference point
• Cooking temperatures — 350 °F equals about 177 °C; many international recipes list Celsius

Tips

1. Memorize a few key benchmarks: 0 °C = 32 °F (freezing), 100 °C = 212 °F (boiling), 20 °C = 68 °F (room temp)
2. For a quick Fahrenheit-to-Celsius estimate, subtract 30 then divide by 2
3. Kelvin is simply Celsius + 273.15, so it is easy to convert between the two mentally
4. When baking with a European recipe, always double-check your oven setting since most US ovens use Fahrenheit
