Celsius To Fahrenheit

Standard Formula

• 1 Start with the temperature in Celsius
• 2 Multiply by 9/5, or multiply by 1.8
• 3 Add 32 to get the Fahrenheit result

Worked Example — 30°C

Weather and daily life

In many countries, weather is reported in Celsius. In the United States, forecasts often use Fahrenheit instead. That means 20°C feels like a comfortable 68°F, while 30°C feels like a hot 86°F day. Knowing a few anchor points makes travel and weather apps easier to read.

• A 0°C = 32°F, freezing weather
• B 20°C = 68°F, comfortable indoor temperature
• C 30°C = 86°F, hot summer weather

Body temperature and cooking

Medical readings and recipes often need tighter precision than weather reports. For body temperature, 37°C equals 98.6°F and 38°C equals 100.4°F. In cooking, 180°C equals 356°F, which is a standard baking temperature in many ovens.

• A 37°C = 98.6°F, average body temperature
• B 38°C = 100.4°F, fever threshold in many contexts
• C 180°C = 356°F, common baking temperature

Weather and travel

If you travel between countries that use different temperature scales, a few memorized conversions can save time. 10°C is 50°F, 20°C is 68°F, and 30°C is 86°F. Those three points cover most daily weather situations.

Health and body temperature

Temperature conversion is common in health tracking, especially if a thermometer or app uses a different scale than you expect. 37°C equals 98.6°F, while 38°C equals 100.4°F. Keep one decimal place when checking medical readings.

Cooking and ovens

Many recipes list oven heat in Celsius, while some ovens display Fahrenheit. 160°C equals 320°F, 180°C equals 356°F, 200°C equals 392°F, and 220°C equals 428°F. These are some of the most used baking and roasting temperatures.

Science and education

Scientific work usually uses Celsius or Kelvin, but textbooks, household products, and older references may still show Fahrenheit. Understanding both scales helps when comparing lab notes, appliance manuals, and educational material.

When rounding is fine

For daily weather, room temperature, and casual conversation, rounding to the nearest whole degree is usually enough. For example, 24°C equals 75.2°F, which most people can read simply as 75°F.

When decimals matter

In cooking, medicine, and technical work, a decimal can matter more. For example, 37°C equals 98.6°F and 38.3°C equals 100.9°F. This page uses the exact formula and rounds only for display.

Celsius

Celsius is used widely in science and in most countries for weather, body temperature, and household measurements. Water freezes at 0°C and boils at 100°C, which makes the scale intuitive for many everyday uses.

Fahrenheit

Fahrenheit is still common in the United States and a few other places. Water freezes at 32°F and boils at 212°F. It uses more degree intervals in everyday weather, which some people find more descriptive for small temperature changes.
