350°F to Celsius: The Classic Baking Temperature
Convert 350°F to Celsius with the exact formula: 350°F equals 176.67°C. The standard US baking temperature and how it maps to metric ovens.
Why 350°F Is the Default Baking Temperature
In the United States, 350°F is the temperature printed on almost every cookie, cake, and casserole recipe. It is the baseline "bake" setting, so converting 350°F to Celsius is something home bakers do constantly when following metric or international recipes.
The answer is 176.67°C. Our temperature converter returns it precisely, and most metric ovens simply round it to 180°C for everyday baking.
The 350°F to Celsius Formula
Fahrenheit to Celsius subtracts 32, then multiplies by 5/9. The 32 removes the offset and the 5/9 rescales the step size to Celsius.
The Exact Calculation
Start with (350 - 32) = 318. Then multiply 318 by 5/9: 318 × 5 = 1590, and 1590 / 9 = 176.666..., which rounds to 176.67°C. The repeating decimal is normal and is why ovens usually show 180°C instead.
The same steps convert any Fahrenheit oven temperature. Only the starting figure changes, so the pattern carries over to 375°F, 400°F, and beyond.
Why 180°C Is the Usual Stand-In
Because 176.67°C is awkward to set, metric recipes and ovens use 180°C as the practical equivalent of 350°F. The 3.3°C gap is tiny in baking terms and will not change most results, which is why the two are treated as interchangeable.
What 176.67°C Means for Cooking
At 350°F (176.67°C), heat penetrates food evenly and surfaces brown at a controlled rate. It is the temperature that sets a cake's crumb while a cookie spreads and crisps at the edge. Almost every "bake at 350" instruction relies on this balance.
For context, 325°F is 162.78°C (slow bake) and 375°F is 190.56°C (hot bake). 350°F sits right in the moderate middle that makes it the universal default.
350°F Compared With Nearby Oven Temps
A quick table helps when adapting recipes. 325°F is 162.78°C, 350°F is 176.67°C, and 375°F is 190.56°C. Each 25°F step is about 14°C.
On the Celsius side, 170°C is 338°F and 180°C is 356°F. So 350°F lands just under 180°C. If you are starting from a Celsius recipe instead, our guide to 180°C to Fahrenheit covers that direction.
Practical Uses of the 350°F Conversion
The conversion matters whenever a US recipe meets a metric oven, or when an American baker follows a British or Australian recipe that lists 180°C. Setting the oven to 180°C reproduces 350°F closely enough for virtually all home baking.
It also helps with conversion charts, cooking apps, and smart ovens that display one scale while a recipe uses the other. Knowing 350°F is 176.67°C (about 180°C) removes the guesswork.
Frequently Asked Questions
What is 350°F in Celsius?
350°F equals 176.67°C, calculated as (350 - 32) × 5/9 = 176.666...°C.
Is 350°F the same as 180°C?
Almost. 350°F is 176.67°C; metric ovens round to 180°C, which is close enough for baking.
How do I convert 350°F to Celsius?
Subtract 32 from 350 to get 318, then multiply by 5/9 to get 176.67°C.
What oven temperature is 350°F?
350°F is the standard moderate "bake" setting in US recipes, used for cakes, cookies, and casseroles.
Why do recipes say 350°F so often?
It is the temperature that browns food evenly without cooking the inside too fast, which suits most baked goods.

Quick Summary
350°F equals 176.67°C. Use the formula Celsius = (Fahrenheit - 32) × 5/9: (350 - 32) × 5/9 = 176.67°C. Metric ovens usually round this to 180°C, which is the practical equivalent for baking.

Disclaimer
Unit conversions on this site use internationally recognized, fixed conversion factors (for example, 1 inch = 2.54 cm, 1 pound = 0.45359237 kg, 1 °F = (°C × 9/5) + 32). They are provided for general, informational, and educational use. For applications where accuracy is critical — such as medical dosing, engineering, scientific research, trade, or legal compliance — always verify results against authoritative sources such as the U.S. National Institute of Standards and Technology (NIST) and the official International System of Units (SI) brochure, and follow any applicable local standards.
Exact Constants & Authoritative Sources
Every conversion on this page uses the fixed, internationally agreed constants below — drawn from NIST and the SI Brochure. No values are estimated or rounded as if exact. See the full list on our Sources & Standards page.
- EXACT°F = °C × 9/5 + 32 (exact linear relation)
- EXACT°C = (°F − 32) × 5/9 (exact inverse relation)
- EXACTKelvin (K) = °C + 273.15 (exact offset)
- EXACTWater freezes at 0 °C = 32 °F and boils at 100 °C = 212 °F
Common Pitfalls & How to Avoid Them
Subtract 32 BEFORE multiplying
°C = (°F − 32) × 5/9. Doing 5/9 × °F − 32 instead gives a wrong answer because the offset must be removed first. Parentheses matter.
Degrees are not the same size
A 1 °C step equals a 1.8 °F step. A "10-degree" forecast difference is 18 °F, not 10 °F. This is why a 5 °C day feels very different from a 15 °C day.
Negative signs
Below freezing, (°F − 32) is negative; keep the sign through the whole calculation. −40 °C = −40 °F is the only point where the two scales meet.
A unit-conversion reference site has no manufacturer-specific or device calibration parameters, so "layered tuning" does not apply here. The only real error-handling is input validation: the converter rejects non-numeric, empty, or out-of-range entries and shows a clear message, then falls back to exact constants above. No estimated or rounded figures are ever presented as exact.
