Oven temperature conversion can be a bit tricky to convert from one unit to another. This article will show you how to convert your oven temperatures using an easy conversion chart.

OVEN TEMPERATURE CONVERSIONS – Fahrenheit, Celsius (fan-assisted), and gas marks.
Everyone seems to have a go-to oven temperature conversion chart. We’ve also found ourselves referring to them regularly. So, we thought we would put our own together. This chart is useful in baking because cooking temperatures vary by oven. This chart will help you convert your temperature to Fahrenheit, Celsius, fan assisted, and gas marks. using the convection or conventional setting of your oven.
If you’re an avid baker and want to be sure that your recipes turn out perfectly every time, it’s important to understand how oven temperatures are measured.
HOW DO MOST OVENS MEASURE TEMPERATURE?
Most ovens use what is called a thermocouple to measure the temperature of your food. A thermocouple is a pair of wires made of different types of metal. If you run electricity through them, they change their length based on the temperature around them. That’s it! That’s how the oven measures temperature. It doesn’t care about the number that it spits out, it only cares about the length

WHAT ARE THE MOST COMMON OVEN TEMPERATURES?
Nowadays, ovens are available with a large variety of temperatures. A lot of people still do not know what cooking temperature to choose for their dishes, so we decided to make a list with the most common oven temperatures.
- 325 °F =170 °C
- 350 °F =180 °C
- 375 °F =190 °C
- 400 °F =200 °C
- 425 °F =220 °C
- 450 °F =230 °C
- 475 °F =240 °C
WHAT IS THE DIFFERENCE BETWEEN CELSIUS AND FAHRENHEIT?
I would like to explain, in layman’s terms, the difference between Celsius and Fahrenheit. Celsius and Fahrenheit are two temperature scales that are used to measure heat. They are both widely used, but in most of the world, Celsius is preferred while in the US Fahrenheit is more widely used. They are based on the same principle, but they use different numbers to indicate the same temperatures.
The main difference between Celsius and Fahrenheit is that the scale of Celsius starts from zero, while the Fahrenheit scale starts from a much higher temperature.
Below is a conversion chart that lists the various oven temperatures in Celsius and Fahrenheit.
OVEN TEMPERATURE CONVERSION CHART
There are lots of different oven temperatures you have to work with when baking. Most recipes will tell you to preheat the oven to a specific temperature, but there are many different kinds of ovens and they all have different temperatures. Here is a simple chart to help you through.
GAS MARK | DEGREE CELSIUS °C | DEGREE CELSIUS FAN °C | DEGREE FAHRENHEIT °F |
1/4 | 110°C | 100°C | 225 °F |
1/2 | 120°C | 110°C | 250 °F |
1 | 140°C | 120°C | 275 °F |
2 | 150°C | 130°C | 300 °F |
3 | 170°C | 140°C | 325 °F |
4 | 180°C | 160°C | 350 °F |
5 | 190 °C | 170°C | 375 °F |
6 | 200 °C | 180°C | 400 °F |
7 | 220 °C | 200°C | 425 °F |
8 | 230 °C | 210°C | 450 °F |
9 | 240 °C | 220°C | 475 °F |
10 | 260 °C | 240°C | 500 °F |
Note that these conversions have been rounded up or down to make measuring easier and this will have very little to no difference in your resulting recipe.
HOW TO CONVERT OVEN TEMPERATURE ROM FAHRENHEIT TO CELSIUS – THE FORMULA
To convert temperatures in degrees Fahrenheit to Celsius, use this formula. Subtract 32 (from the given temperature) and multiply by .5556 (or 5/9)
C=(F-32) X 5⁄9 or C=(F-32) X .5556
Example: (350°F — 32) x .5556 = 176.6808°C
On the chart, 350°F is rounded up to 180°C
HOW TO CONVERT OVEN TEMPERATURE FROM CELSIUS TO FAHRENHEIT – THE FORMULA
To convert temperatures in degrees Celsius to Fahrenheit, use this formula. Multiply by 1.8 or 9/5 (from the given temperature) and add 32
F = C(9⁄5) + 32 or F=(Cx1.8) +32
Example: (220°C x 1.8) + 32 = 428°F
On the chart, 220°C is rounded down to 425°F degrees
