Celsius to Fahrenheit Converter — Free & Instant

What This Tool Does

This tool converts a temperature in Celsius to Fahrenheit using the standard formula (°F = °C × 9/5 + 32). It's built for the most common everyday reasons this comes up: checking weather forecasts from US sources, converting oven temperatures in American recipes, or making sense of a body temperature reading against the US convention.

How to Use It

Type your temperature in Celsius into the value field (the tool is pre-set to convert Celsius → Fahrenheit).
Press Convert.
Your result in Fahrenheit appears instantly. Need a different unit pair? The Category, From and To dropdowns above the result still work if you want to switch.

Example

An American recipe calling for an oven at 180°C converts to 356°F — close enough to round to the nearest common oven setting (350°F), which is why US recipes and Indian recipes can look like they're using completely different numbers for the same actual oven heat.

Frequently Asked Questions

What is the exact formula?

°F = (°C × 9/5) + 32. So 0°C (freezing point of water) equals 32°F, and 100°C (boiling point) equals 212°F.

Is normal human body temperature 37°C or 98.6°F?

Both describe the same commonly cited average body temperature — 37°C converts to exactly 98.6°F using the formula above, though normal body temperature actually varies slightly by person and time of day.

Why does the US use Fahrenheit while most of the world uses Celsius?

The United States is one of the few countries that never switched to the Celsius scale used almost everywhere else, a holdover from before most nations standardised on the metric system in the 20th century.
