How do I convert Fahrenheit to Celsius?

Quick explanation

Use this page when a recipe is in Fahrenheit and your oven is set in Celsius. The exact conversion gives precision, while practical rounded values are often easier to use on real oven controls. This converter helps you move quickly between US and metric recipe formats without guesswork. For reverse conversion, use Celsius to Fahrenheit or see fixed pages like 350°F to C and 400°F to C.

Calculation steps

How to convert Fahrenheit to Celsius manually

°C = (°F - 32) × 5/9

Subtract 32 first, then multiply by 5 and divide by 9.

Practical oven rounding

Round to the nearest practical Celsius setting your oven supports.

Most home ovens do not need long decimal precision for everyday baking and roasting.

Worked example

Input: 350

(350 - 32) × 5/9 = 176.7°C.

Practical: 350°F is often rounded to 175°C or 180°C.

About these units

Fahrenheit (°F)

Fahrenheit is common in US recipes and oven guides. You will often see exact values in recipe instructions and printable charts.

350°F is a common moderate baking temperature.
400°F is often used for hotter roasting and stronger browning.

Celsius (°C)

Celsius is standard in Canada and many international kitchens. Converting to °C helps match local oven controls and avoid cooking-time errors.

Around 175°C to 180°C is commonly used for 350°F recipes.
Around 200°C to 205°C is commonly used for 400°F recipes.

Tips

Common oven temps: 350F ~ 175C and 400F ~ 200C.

Decimals are exact; measuring tools aren’t. Rounding to common fractions is often the practical choice.

If you notice uneven browning, rotate the tray halfway through baking.
