Convert Celsius to Fahrenheit for cooking, weather, science, and medicine. Understand why the US uses Fahrenheit, conversion tricks, and common temperature references.
Formula: °F = °C × (x × 9/5) + 32
The Celsius to Fahrenheit conversion is one of the most common temperature conversions needed in daily life. While most of the world uses Celsius, the United States, Bahamas, Belize, Cayman Islands, and Palau still use Fahrenheit. This converter helps you navigate between these systems for cooking, weather interpretation, scientific work, and medical applications.
Temperature conversion affects many aspects of international communication and daily life. From following American recipes to understanding US weather forecasts, interpreting medical information, or working with international colleagues in science and industry, accurate temperature conversion is essential. The 180-degree span between water's freezing and boiling points in Fahrenheit versus 100 degrees in Celsius creates frequent confusion.
Recipe conversion between American and international cookbooks is one of the most common uses for C to F conversion. Precise oven temperatures are crucial for successful baking.
Understanding weather forecasts when traveling or communicating internationally requires temperature conversion. Climate data comparison also needs accurate conversion.
Medical temperature readings, fever thresholds, and medication storage requirements often need conversion between systems, especially for international patients or imported medications.
The Celsius is a widely used unit for measuring temperature. It is commonly used in various applications and industries worldwide.
The Fahrenheit is a widely used unit for measuring temperature. It is commonly used in various applications and industries worldwide.

The US adopted Fahrenheit early in its history, and by the time the metric system gained global acceptance, the cost of converting every thermometer, weather station, oven, and documentation was deemed too high. Additionally, Fahrenheit provides more whole number precision for everyday temperatures - the range of livable temperatures (0-100°F) has 100 increments versus about 55 in Celsius (-18 to 38°C).
For rough estimates: double the Celsius, subtract 10%, and add 32. For example: 20°C × 2 = 40, minus 10% (4) = 36, plus 32 = 68°F. The actual answer is 68°F, so this method works well for everyday use. For more precision, remember key points: 0°C=32°F, 10°C=50°F, 20°C=68°F, 30°C=86°F.
Fahrenheit originally set human body temperature at 96°F on his scale. Later, more accurate measurements showed normal body temperature as 98.6°F (37°C). This precise decimal comes from converting the round Celsius number. Interestingly, recent studies suggest average human body temperature has dropped to about 97.9°F (36.6°C) since the 1800s.
Fahrenheit provides more precision without decimals. Each Celsius degree equals 1.8 Fahrenheit degrees, so Fahrenheit has almost twice the resolution. For example, 20-21°C spans 68-69.8°F, giving Fahrenheit 3 whole number options (68, 69, 70°F) versus Celsius's 2 (20, 21°C). This is why some argue Fahrenheit is better for weather and human comfort ranges.
No, oven temperatures vary by country and type. US ovens use Fahrenheit, while most others use Celsius. Additionally, gas ovens often use 'gas marks' in the UK (Gas Mark 4 = 350°F = 180°C). Fan/convection ovens typically run 20-25°C (35-45°F) hotter than conventional ovens, so recipes often specify which type they're written for.
