Oven Temperature Guide: Celsius to Fahrenheit for Baking

June 19, 2025 โ€ข 4 min read

You have found a beautiful recipe online, but the oven temperature is in Celsius and yours displays Fahrenheit (or the other way around). This is one of the most common conversion problems in the kitchen. Here is your complete reference.

Oven Temperature Chart

  • โ–ถ Very low: 120ยฐC = 250ยฐF (Gas Mark 1/2)
  • โ–ถ Low: 150ยฐC = 300ยฐF (Gas Mark 2)
  • โ–ถ Moderate: 160ยฐC = 325ยฐF (Gas Mark 3)
  • โ–ถ Moderate: 180ยฐC = 350ยฐF (Gas Mark 4)
  • โ–ถ Moderately hot: 190ยฐC = 375ยฐF (Gas Mark 5)
  • โ–ถ Hot: 200ยฐC = 400ยฐF (Gas Mark 6)
  • โ–ถ Hot: 220ยฐC = 425ยฐF (Gas Mark 7)
  • โ–ถ Very hot: 230ยฐC = 450ยฐF (Gas Mark 8)
  • โ–ถ Extremely hot: 250ยฐC = 480ยฐF (Gas Mark 9)

The Formula

ยฐF = (ยฐC ร— 9/5) + 32

ยฐC = (ยฐF - 32) ร— 5/9

Common Baking Temperatures

Most recipes fall into a few standard temperatures:

  • โ–ถ Cookies: 180ยฐC / 350ยฐF โ€” the most common baking temperature
  • โ–ถ Cakes: 160-180ยฐC / 325-350ยฐF
  • โ–ถ Bread: 200-230ยฐC / 400-450ยฐF
  • โ–ถ Pizza: 220-250ยฐC / 425-480ยฐF (as hot as home ovens go)
  • โ–ถ Meringues: 100-120ยฐC / 210-250ยฐF (very low and slow)
  • โ–ถ Roast chicken: 200ยฐC / 400ยฐF
  • โ–ถ Slow roast: 150ยฐC / 300ยฐF

Fan Oven Adjustment

If your recipe gives a temperature for a conventional oven but you have a fan (convection) oven, reduce the temperature by 20ยฐC (or about 25ยฐF). Fan ovens circulate hot air, cooking food faster and more evenly.

  • โ–ถ Recipe says 200ยฐC conventional = use 180ยฐC fan
  • โ–ถ Recipe says 180ยฐC conventional = use 160ยฐC fan
  • โ–ถ Recipe says 400ยฐF conventional = use 375ยฐF fan

Tips for Accurate Oven Temperatures

  • โ–ถ Get an oven thermometer โ€” most ovens are off by 10-25ยฐF from what the dial says
  • โ–ถ Always preheat โ€” give your oven at least 10-15 minutes to reach temperature
  • โ–ถ Avoid opening the door โ€” each opening drops temperature by 25ยฐF (14ยฐC)
  • โ–ถ Know your hot spots โ€” rotate trays halfway through baking for even results
