About Temperature Conversion

Need to convert temperatures between Fahrenheit and Celsius? You're in the right place. This converter handles both directions instantly—whether you're checking the weather, following a recipe, or working on a science project.

Fahrenheit was created by Daniel Gabriel Fahrenheit in 1724. It's still the main scale in the United States and a handful of other countries. Water freezes at 32°F and boils at 212°F. For everyday weather, Fahrenheit gives you more detail in the temperature ranges people actually experience.

Celsius (sometimes called centigrade) came from Swedish astronomer Anders Celsius in 1742. Most of the world uses it now, and it's the standard in science. Water freezes at 0°C and boils at 100°C—nice and simple with its decimal system. To convert between them, use: °C = (°F - 32) × 5/9.

Cooking is probably where most people need this. Recipes from different countries use different scales. Baking at 350°F? That's 177°C. Cooking a steak to rare (125°F) means getting it to about 52°C. Well-done is around 160°F or 71°C. Getting these right matters for food safety and getting the results you want.

Scientists often need to convert temperatures when sharing data or working with equipment from different countries. Most journals want Celsius or Kelvin, so if your lab gear uses Fahrenheit, you'll need to convert. Same goes for weather data, environmental monitoring, or any research that spans borders.

Weather apps and forecasts use different scales depending on where you are. A comfortable room is around 68-72°F (20-22°C). A hot day might hit 86-95°F (30-35°C). And everyone knows 32°F (0°C) means freezing—time to bundle up.

Travelers run into this all the time. Check the weather before your trip and you'll see temperatures in whatever scale that country uses. A quick conversion helps you pack the right clothes and know what to expect when you arrive.

Doctors and nurses sometimes need to convert body temperatures. Normal is 98.6°F or 37°C. A fever typically starts around 100.4°F (38°C). Medical equipment from different manufacturers might use different scales, so conversion helps keep records consistent.

This converter works offline, so you can use it anywhere. It's simple—no complicated formulas to remember. Just type in a temperature and get your answer. We've included common reference points too, so you can double-check your conversions against temperatures you already know.
