How to Convert Fahrenheit to Celsius for Oven

Whether you're following an American recipe in a UK kitchen or vice versa, converting oven temperatures between Fahrenheit and Celsius is a skill every home cook needs. Here's the formula, a full conversion table, and tips for getting it right every time.

The Conversion Formula

• Fahrenheit to Celsius: (°F − 32) ÷ 1.8 = °C
• Celsius to Fahrenheit: (°C × 1.8) + 32 = °F

For example: 350°F − 32 = 318 ÷ 1.8 = 176.6°C ≈ 180°C

Oven Temperature Conversion Table: °F to °C

• 200°F → 93°C (very low / warming)
• 250°F → 120°C (very low)
• 275°F → 135°C (low)
• 300°F → 150°C (low)
• 325°F → 165°C (moderate-low)
• 350°F → 180°C (moderate — most common baking temp)
• 375°F → 190°C (moderate-high)
• 400°F → 200°C (hot)
• 425°F → 220°C (hot)
• 450°F → 230°C (very hot)
• 475°F → 245°C (very hot)
• 500°F → 260°C (extremely hot / pizza temp)

Common Baking Temperatures at a Glance

• Cakes and muffins: 325–350°F / 165–180°C
• Cookies and biscuits: 350–375°F / 180–190°C
• Bread: 375–425°F / 190–220°C
• Roast chicken: 375–400°F / 190–200°C
• Roast beef: 325–375°F / 165–190°C
• Pizza: 450–500°F / 230–260°C
• Fish fillets: 375–400°F / 190–200°C

Fan Oven Adjustment

If your recipe specifies a conventional oven temperature and you're using a fan oven, remember to reduce the temperature by 20°C (25°F) after converting. For example, a recipe calling for 350°F (180°C) conventional becomes 160°C (325°F) in a fan oven.

Why Your Converted Temperature May Still Be Off

Oven thermostats are notoriously inaccurate — your oven may run 10–25°C hotter or cooler than the dial indicates. After converting your temperature, always verify the actual oven temperature with a thermometer.

The Oven Thermometer 2 Pack (50–300°C / 100–600°F) reads in both Celsius and Fahrenheit, making it the perfect tool for cross-checking your converted temperatures in real time.

Quick Mental Shortcuts

• 350°F ≈ 180°C (the most common baking temperature — memorise this one)
• 400°F ≈ 200°C (standard roasting temperature)
• 450°F ≈ 230°C (high heat for pizza and bread)

Summary

To convert °F to °C: subtract 32, then divide by 1.8. The most important temperature to remember is 350°F = 180°C. Always verify your oven's actual temperature with a thermometer, and adjust by 20°C if switching between fan and conventional modes.
