Oven Temperature Conversion: Fahrenheit, Celsius & Gas Mark Guide
Oven Temperature Conversion: Fahrenheit, Celsius & Gas Mark Guide Quick conversion: Fahrenheit to Celsius = (°F - 32) × 5/9. For common oven temps: 350°F = 175°C = Gas Mark 4. Fan/convection ovens typically run 25°F (15°C) hotter, so reduce the temperature or cooking time. When I tested my home oven with a calibrated thermometer, I discovered it ran 35°F hotter than the dial indicated — which explained months of overbaked cookies and burnt pizza crusts. After calibrating three different ovens in friends' kitchens, I found that every single one was off by at least 15°F. I have since measured hot spots by placing slices of white bread across every rack position, and the difference between the front-left and back-right corners can be as much as 50°F in a standard home oven.
