Fahrenheit to Celsius Converter
350°F = 177°C
Reference Table
Temperature Scale
Context & Usage
US recipes almost always use Fahrenheit, while most of the rest of the world bakes in Celsius, making this one of the most-needed conversions in the kitchen.
Oven temperature accuracy matters most for baking, where a 10–15 degree difference can change how a cake or bread rises.
A quick mental estimate — subtract 30 and halve the result — gets close enough for casual conversation, but baking and candy work benefit from the exact formula since a rounded shortcut can drift several degrees off at higher temperatures.
A Worked Example
Say a recipe from a British baking blog calls for a 190°C oven. Subtract 32 after converting — actually, apply the formula directly to your target: (190 × 9/5) + 32 = 374°F, close enough to round to 375°F on a US dial, a common moderate-hot baking temperature for cookies and quick breads.
Standards and Sources
The Fahrenheit scale, still used domestically in the US, was defined by physicist Daniel Gabriel Fahrenheit in 1724, originally calibrated using a brine mixture as its zero point.
The Celsius scale, used almost everywhere else, was proposed by Anders Celsius in 1742 and later adjusted to set water's freezing point at exactly 0° and boiling point at 100° at standard atmospheric pressure.
NIST maintains the precise mathematical relationship between the two scales, which is the exact formula (°C = (°F − 32) × 5/9) this converter uses rather than a rounded approximation.
Where This Shows Up
This conversion comes up constantly for home cooks following recipes from international food blogs or cookbooks, nearly all of which list oven temperatures in Celsius.
US appliance manufacturers selling ovens internationally frequently include a dual-scale dial or digital toggle, making this conversion something users only need once to set a permanent preference.
Common Mistakes
- Rounding 180°C to 350°F without checking the precise conversion (which is actually 356°F), a small gap that rarely matters but occasionally affects delicate bakes.
- Forgetting that a fan or convection oven may need a further adjustment beyond the basic Fahrenheit-Celsius conversion.
- Confusing this scale conversion with a completely different measurement, like gas mark, which requires a lookup table rather than a formula.

Frequently Asked Questions
What is 350°F in Celsius?+
350°F is 177°C, a common moderate baking temperature.
What is the formula for Fahrenheit to Celsius?+
Subtract 32, then multiply by 5/9: °C = (°F − 32) × 5/9.
Is 180°C the same as 350°F?+
Close — 180°C is actually 356°F, but recipes often round to 350°F as the nearest common oven setting.
Is there a quick mental shortcut for this conversion?+
Subtract 30 from the Fahrenheit figure and divide by 2 for a rough estimate — close enough for casual use, though not for precise baking.
Does this conversion change based on altitude?+
No, the Fahrenheit-Celsius relationship is fixed. Altitude affects boiling points and cooking times, not the temperature scale conversion itself.
