When reading recipes on different sites or in a cookbook you almost always stumble upon the fact that different parts of the world are using different temperature scales to tell which temperature to use when baking in your oven. To make it easier for you, here is an oven temperature conversion chart you can use the next time you are baking or cooking.
|Oven Temperature Conversion Chart|
|275 degrees F||140 degrees C||Gas Mark 1|
|300 degrees F||150 degrees C||Gas Mark 2|
|325 degrees F||165 degrees C||Gas Mark 3|
|350 degrees F||177 degrees C||Gas Mark 4|
|375 degrees F||190 degrees C||Gas Mark 5|
|400 degrees F||200 degrees C||Gas Mark 6|
|425 degrees F||220 degrees C||Gas Mark 7|
|450 degrees F||230 degrees C||Gas Mark 8|
|475 degrees F||245 degrees C||Gas Mark 9|
|500 degrees F||260 degrees C||Gas Mark 10|
What is Fahrenhet?
Fahrenheit is a temperature scale which was proposed in 1724 by physicist Daniel Gabriel Fahrenheit. 0 °F was established as the temperature of a solution of brine made out of equal parts ice, water and salt. 32 °F was defined as the temperature at which ice melts. Nowadays the scale is measured between two fixed points. The first one being where water freezes into ice (32 °F) and the other where water reaches the boiling point (212 °F).
Fahrenheit is mainly used in the United States and its unincorporated territories.
What is Celsius?
Celsius is a temperature scale that is used by the International System of Units (SI). It is named after the Swedish (yeah!) astronomer Anders Celsius. 0 °C is the point where water freezes into ice and 100 °C is the point at which water starts to boil.
What is Gas Mark?
Gas Mark is the common term used in Great Britain, Ireland and some of the Commonwealth nations. It’s used for ovens that use gas (hence the name) rather than electricity to get hot. It’s not completely clear how the term came to be, but it is known to be used as early as 1943. Gas Mark 1 is the equivalent of 275 °F (140 °C). Each time the gas mark increases with one (1) step the temperature rises with 25 °F (13,9 °C).
Convert by yourself
If you feel like doing some math (and who doesn’t?) you can convert the temperatures by using the following formula:
T°F = (9/5) * T°C + 32
T°C = (5/9) * (T°F – 32)
T°C = (G * 14) + 121
Example: To convert 300 °F to Celsius you do the following:
(5/9) * (300 – 32) = 148.88888888888888 ≈ 150
Now that you know, you can head over to the baking recipes and bake away!
