425°F to Celsius: What 425 Degrees Fahrenheit Equals

Convert 425°F to Celsius: 425 degrees Fahrenheit equals 218.33°C. Learn the formula and what a hot 425°F oven setting means.

Why 425°F Comes Up

Four hundred twenty-five degrees Fahrenheit is a hot oven setting used for roasted chicken, vegetables, and pastries that should brown hard and fast. The Celsius value is a common kitchen lookup.

The answer is 218.33°C. Our Fahrenheit to Celsius converter returns it directly; 218.33°C is the rounded figure.

The 425°F to Celsius Formula

To convert Fahrenheit to Celsius, subtract 32, then multiply by 5/9. The minus 32 lines up the zero points, since water freezes at 32°F but 0°C.

The Exact Calculation

Start with (425 - 32) = 393. Then 393 × 5/9 = 1965/9 = 218.333...°C, rounded to 218.33°C.

The same pattern works for any Fahrenheit value: subtract 32, then multiply by 5/9.

Where 425°F Appears

This temperature is a favorite for roasted chicken and root vegetables, and for puff pastry that needs a strong initial heat.

What 218.33°C Means in the Kitchen

At 218.33°C (425°F), food browns and crisps quickly, a dependable hot setting for roasting. It is a common hot anchor on US oven dials.

For the hotter 450°F mark, our guide to 450°F to Celsius covers the 232.22°C setting.

425°F Compared With Nearby Temperatures

Nearby values: 400°F is 204.44°C, 450°F is 232.22°C, and 475°F is 246.11°C. Each Fahrenheit degree is 5/9 of a Celsius degree.

In the oven, 425°F is the hot end, a useful anchor when switching between US and metric recipes.

When You Need 425°F in Celsius

The conversion matters for roasting. A US recipe at 425°F is 218.33°C on a metric oven; a metric recipe at 220°C is close to 428°F.

It also helps when a European appliance lists 220°C and you want the Fahrenheit figure for a US dial.

Frequently Asked Questions

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.
