How to Use This Celsius to Fahrenheit Converter
Our Celsius to Fahrenheit converter gives you instant, accurate temperature conversions for cooking, weather, science, medicine, and travel. Enter any temperature in degrees Celsius and the tool calculates the exact Fahrenheit equivalent. Click swap to reverse the conversion. The copy button lets you paste the result directly into recipes, weather apps, or lab reports.
Below the converter, you will find a comprehensive table of common Celsius to Fahrenheit conversions. This covers everyday temperatures from freezing cold to oven hot. Whether you are baking a cake from a British recipe, checking the weather forecast for a US trip, or monitoring a fever, this reference table has you covered.
Celsius to Fahrenheit Conversion Formula
The Celsius and Fahrenheit scales are both based on the freezing and boiling points of water, but they use different intervals. Celsius sets water freezing at 0° and boiling at 100°. Fahrenheit sets water freezing at 32° and boiling at 212°. The conversion formula bridges these two scales.
Fahrenheit = (Celsius × 9/5) + 32
Example: 25°C × 1.8 + 32 = 77°F
For the reverse — Fahrenheit to Celsius — subtract 32 first, then multiply by 5/9. A recipe calling for 350°F equals 176.7°C. A summer day of 86°F equals 30°C. Our converter handles both directions instantly.
Common Uses for Celsius to Fahrenheit Conversion
Cooking and Baking
International recipes are the #1 reason people search for Celsius to Fahrenheit converters. European, Australian, and Canadian recipes list oven temperatures in Celsius. A moderate oven of 180°C equals 356°F. A hot oven of 220°C equals 428°F. If you set your US oven to 180°F instead of 356°F, your cake will never bake.
Meat thermometers also vary by region. Safe internal temperature for chicken is 74°C (165°F). Medium-rare steak is 57°C (135°F). When using a Celsius thermometer in an American kitchen — or vice versa — accurate conversion is essential for food safety.
Weather and Travel
Weather forecasts use Celsius in most countries and Fahrenheit in the US. A comfortable room temperature of 22°C equals 71.6°F. A hot summer day of 35°C equals 95°F. A freezing winter day of -10°C equals 14°F. When traveling between regions, quick conversion helps you pack the right clothes.
If you are traveling from Europe to the US and see a forecast of 80°F, that is roughly 27°C — warm but not extreme. If you see 100°F, that is 38°C — dangerously hot. Our converter helps you interpret foreign weather reports instantly.
Health and Medicine
Body temperature is one of the most critical conversions. Normal human body temperature is 37°C, which equals 98.6°F. A fever starts at 38°C (100.4°F). A high fever of 40°C equals 104°F. Medical thermometers sold in different regions display in different units, so parents and caregivers need to convert quickly.
Medication storage temperatures are also important. Many vaccines must be stored between 2°C and 8°C (35.6°F to 46.4°F). Insulin should be kept between 2°C and 25°C (36°F to 77°F). If you are traveling with medication, knowing these conversions ensures proper storage.

Frequently Asked Questions
What is the formula for Celsius to Fahrenheit?
The formula for converting Celsius to Fahrenheit is: Fahrenheit = (Celsius × 9/5) + 32. For example, 20°C × 9/5 = 36, then 36 + 32 = 68°F.
How do I convert Celsius to Fahrenheit quickly?
For a quick mental estimate, double the Celsius temperature and add 30. For example, 20°C → 20 × 2 + 30 = 70°F (actual: 68°F). This gives you a ballpark within 2-4 degrees.
What is 37°C in Fahrenheit?
37 degrees Celsius equals 98.6 degrees Fahrenheit. This is normal human body temperature.
What is 0°C in Fahrenheit?
0 degrees Celsius equals 32 degrees Fahrenheit. This is the freezing point of water.
What is 100°C in Fahrenheit?
100 degrees Celsius equals 212 degrees Fahrenheit. This is the boiling point of water at sea level.
At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit are equal at -40 degrees. -40°C = -40°F. This is the only temperature where both scales show the same number.
Which countries use Celsius vs Fahrenheit?
