celsius to fahrenheit
Convert °C to °F for weather, ovens, and body temperature in US terms.
To convert Celsius to Fahrenheit, multiply by 9/5 and add 32. In symbols, °F = (°C × 9/5) + 32. This free celsius to fahrenheit converter applies that formula instantly. Use it for weather apps, recipes, and fever checks when the source is metric and you need a US Fahrenheit reading. Weather, cooking, and fever checks are the three US uses that show up most often.
How to convert celsius to fahrenheit
Use °F = (°C × 9/5) + 32. Multiply Celsius by 1.8, then add 32.
Example: 20 × 1.8 + 32 = 68. So 20°C equals 68°F.
Do not reverse those steps. Multiply first, then add 32. Weather gaps near freezing deserve careful conversion.

Common Celsius to Fahrenheit conversions
0°C is 32°F, the freezing point of water. 100°C is 212°F, the boiling point at standard pressure.
20°C is 68°F, a mild indoor or outdoor reading. 37°C is 98.6°F, the classic body-temperature reference.
38°C is 100.4°F. Many people treat that area as a fever threshold on household charts.
Oven temperatures should still follow the appliance manual after you convert a recipe value.
Why the US still reports weather in Fahrenheit
US forecasts, ovens, and school health notes still default to Fahrenheit. Most other countries publish the same conditions in Celsius.
Converting Celsius to Fahrenheit keeps metric data usable for US habits. It is the quick step between international sources and local expectations.
For fever tracking, convert with the same method each time. Consistency matters more than extra decimal places.
Recipe sites from abroad often list oven heat in Celsius. Convert before you set a US oven dial.
A weather report of 30°C is 86°F. That single check helps plan outdoor work in US terms.
For fever tracking, convert with the same method each time. Consistency matters more than extra decimals.
Keep the formula nearby: multiply by 9/5, then add 32 for any Celsius value.
