Degrees to Gas Mark Calculator

This degrees to gas mark calculator converts between oven temperature in degrees Celsius and the UK gas mark system. The gas mark system is a simplified way to indicate oven temperatures, with each mark representing a specific range of temperatures.

How to Use the Degrees to Gas Mark Calculator

Using the degrees to gas mark calculator is simple:

Enter the temperature in degrees Celsius in the input field.
Click the "Calculate" button to convert the temperature to a gas mark.
The result will display the corresponding gas mark and the temperature range it represents.

The calculator will show you the exact gas mark that matches your input temperature, or indicate if the temperature is outside the standard gas mark range.

Conversion Formula

The gas mark system in the UK is based on the following temperature ranges:

Gas Mark 1: 120°C to 140°C
Gas Mark 2: 140°C to 160°C
Gas Mark 3: 160°C to 180°C
Gas Mark 4: 180°C to 200°C
Gas Mark 5: 200°C to 220°C
Gas Mark 6: 220°C to 240°C
Gas Mark 7: 240°C to 260°C
Gas Mark 8: 260°C to 280°C
Gas Mark 9: 280°C to 300°C

Formula

Gas Mark = ROUND((Temperature - 120) / 20) + 1

Where Temperature is in degrees Celsius

For example, a temperature of 175°C would be calculated as:

(175 - 120) / 20 = 2.75 → ROUND(2.75) = 3 → Gas Mark 3

Gas Mark to Temperature Chart

The following chart shows the temperature ranges for each gas mark:

Note: Gas mark 0 is not included in this chart as it represents a temperature below 120°C, which is not commonly used for cooking.

Gas Mark	Temperature Range (°C)
1	120°C - 140°C
2	140°C - 160°C
3	160°C - 180°C
4	180°C - 200°C
5	200°C - 220°C
6	220°C - 240°C
7	240°C - 260°C
8	260°C - 280°C
9	280°C - 300°C

Common Cooking Temperatures

Here are some common cooking temperatures and their corresponding gas marks:

Baking potatoes: 180°C (Gas Mark 4)
Roasting chicken: 190°C (Gas Mark 4-5)
Browning meat: 200°C (Gas Mark 5)
Roasting vegetables: 220°C (Gas Mark 6)
Baking bread: 230°C (Gas Mark 6-7)
Melting chocolate: 180°C (Gas Mark 4)
Cooking pasta: 100°C (Below Gas Mark 1)

Note: Some recipes may require temperatures outside the standard gas mark ranges. Always check your recipe for specific temperature requirements.

Frequently Asked Questions

What is the difference between gas marks and degrees Celsius?

Gas marks are a simplified way to indicate oven temperatures in the UK. Each gas mark represents a specific range of temperatures in degrees Celsius. For example, Gas Mark 4 corresponds to temperatures between 180°C and 200°C.

Can I use the gas mark system in other countries?

The gas mark system is specific to the UK and may not be recognized or used in other countries. Different countries have their own systems for indicating oven temperatures.

What if my oven doesn't have a gas mark indicator?

If your oven doesn't have a gas mark indicator, you can use this calculator to convert the temperature you need to a gas mark. This will help you set your oven to the correct temperature range.

Are there any safety considerations when using high oven temperatures?

Yes, high oven temperatures can be dangerous. Always follow safety guidelines when using your oven, and never leave food unattended in the oven. Use oven mitts and potholders when handling hot pans and dishes.
