Fahrenheit to Celsius Quick Converter – Oven Temps & Weather

The formula is: °C = (°F − 32) × 5/9. First subtract 32 from the Fahrenheit value, then multiply the result by 5, and finally divide by 9. For example, to convert 350°F: (350 − 32) = 318, then 318 × 5 = 1590, then 1590 ÷ 9 = 176.67°C (approximately 177°C). Our converter above does this calculation instantly.

The most common oven temperatures are: 350°F (177°C) for general baking, 375°F (191°C) for roasting vegetables, 400°F (204°C) for crispy roasting, 425°F (218°C) for pizza and high-heat roasting, and 300°F (149°C) for slow cooking. Most recipes use 350°F as the standard moderate oven setting. Use the quick-select buttons above to instantly see the conversion for any oven temperature.

The United States continues to use Fahrenheit primarily due to historical precedent and cultural inertia. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724 and was widely adopted in English-speaking countries. While most nations switched to Celsius during the metrication movements of the 20th century, the U.S. maintained Fahrenheit for everyday temperature measurements. Many Americans find Fahrenheit more intuitive for weather and body temperature because its 0–100 range roughly corresponds to typical weather conditions in temperate climates.

Normal body temperature is 98.6°F (37°C). However, normal body temperature can range from 97°F (36.1°C) to 99°F (37.2°C) depending on the individual, time of day, and activity level. A fever is generally considered to be 100.4°F (38°C) or higher. The 98.6°F standard was established by German physician Carl Wunderlich in the 19th century based on over a million measurements.

Water freezes at 32°F (0°C) and boils at 212°F (100°C) at standard atmospheric pressure (sea level). This 180-degree span between freezing and boiling points in Fahrenheit is one reason some prefer it—it allows for finer gradation without decimals. At higher altitudes, water boils at lower temperatures due to reduced atmospheric pressure. For every 500 feet (152 meters) of elevation gain, the boiling point drops by about 1°F (0.5°C).

For a quick mental estimate: subtract 30 from the Fahrenheit value, then halve it. Example: 70°F → 70 − 30 = 40, then 40 ÷ 2 = 20°C (actual is 21.1°C). For Celsius to Fahrenheit: double the Celsius value, then add 30. Example: 20°C → 20 × 2 = 40, then 40 + 30 = 70°F (actual is 68°F). This shortcut is accurate within a few degrees for typical weather temperatures. For precise conversions, use our converter above.

Most artisan breads bake at 425–450°F (218–232°C) for a crispy crust. Sandwich loaves and soft dinner rolls typically bake at 350–375°F (177–191°C). Pizza benefits from very high heat—450–500°F (232–260°C) or higher. Always preheat your oven fully before baking, and use an oven thermometer to verify the actual temperature, as many ovens run 25–50°F off from the set temperature.

Yes! Fahrenheit and Celsius are equal at −40°. At −40°F = −40°C, both scales intersect. This is the only temperature where the two scales give the same numerical reading. This occurs because the conversion formula °C = (°F − 32) × 5/9 yields the same value when both are −40: (−40 − 32) × 5/9 = (−72) × 5/9 = −40.
