425°F to °C — What is 425 Fahrenheit in Celsius?
425°F = 218.33°C. Use the exact formula (°F − 32) × 5/9 to convert any Fahrenheit temperature to Celsius — algebraically exact with zero rounding, as defined by the NIST.
Answer
425 °F = 218.33 °C
Exact: 218.330000 °C · uses the BIPM-defined constant
How it's calculated
(°F − 32) × 5/9 = °C
Step 1: Apply the formula to the input value.
Step 2: (425 − 32) × 5/9 = 393 × 5/9 = 218.33
What does 425°F feel like?
425°F is an oven or high-heat cooking temperature. The Maillard browning reaction starts around 280°F, and most baking occurs between 325–450°F. At 425°F, food cooks and browns rapidly.
