Understanding Gas Marks

Gas Marks are used on gas ovens, primarily in the UK and Europe. Each mark represents approximately 25°F (14°C) increase.

Gas Mark ½250°F • 120°C
Gas Mark 2300°F • 150°C
Gas Mark 4350°F • 177°C ⭐
Gas Mark 6400°F • 200°C
Gas Mark 8450°F • 230°C

💡 Fun Fact: Gas Mark 4 (350°F/177°C) is called "moderate oven" - the sweet spot for most baking!

Fan Oven Adjustments

Fan-assisted (convection) ovens circulate hot air, cooking food faster and more evenly.

📐 Conversion Rule:

Option 1: Reduce temp by 25°F (15°C)

Example: 350°F → 325°F fan

Option 2: Reduce time by 10-15%

Example: 60 min → 50-55 min

Recipe says 350°F conventional:

Set fan oven to325°F (163°C)

Recipe says 400°F conventional:

Set fan oven to375°F (191°C)

⚠️ Tip: Always verify with an oven thermometer - individual ovens can vary by ±25°F!

How to Convert Temperature

The Formula

°C = (°F - 32) × 5/9

Example Calculation:

Problem: Convert 350°F to Celsius

Step 1: 350 - 32 = 318

Step 2: 318 × 5/9 = 176.67

Answer: ≈ 177°C (moderate oven)

Quick Mental Math Tricks

🧮Trick #1: Subtract 30, halve it

For rough estimates: (°F - 30) ÷ 2

Example: 100°F: (100-30)÷2 = 35°C
(Actual: 37.8°C - close!)

📊Trick #2: Remember Benchmarks

Memorize key temperature points

32°F = 0°C (Freezing)
212°F = 100°C (Boiling)
98.6°F = 37°C (Body temp)

Understanding Temperature Scales

🇺🇸

Fahrenheit

Created: 1724 by Daniel Gabriel Fahrenheit

Used in: United States, Cayman Islands, Bahamas, Palau

Scale: Water freezes at 32°F, boils at 212°F (180° difference)

Best for: Daily weather (finer granularity for comfort range)

🌍

Celsius

Created: 1742 by Anders Celsius

Used in: Worldwide (except US and a few others)

Scale: Water freezes at 0°C, boils at 100°C (100° difference)

Best for: Science, international communication (metric system)

Why Different Scales Exist

Fahrenheit was designed with 0°F as the coldest temperature achievable with a brine solution, and 100°F as human body temperature (later refined to 98.6°F). This made sense for daily life in the 1720s.

Celsius was designed around water's freezing and boiling points, making it more logical for scientific work. Today, most of the world uses Celsius for its simplicity, while the US maintains Fahrenheit for historical and cultural reasons.

Frequently Asked Questions

What is 350°F in Celsius?

350°F = 177°C (or 176.67°C precisely). This is the most common baking temperature, equivalent to Gas Mark 4. It's called 'moderate oven' and is perfect for cakes, cookies, and most baked goods.

How do I convert Fahrenheit to Celsius?

Use the formula: °C = (°F - 32) × 5/9. For example: (350°F - 32) × 5/9 = 176.67°C ≈ 177°C. For quick mental math, subtract 30 and divide by 2 for a rough estimate: (350-30)÷2 ≈ 160°C.

What are Gas Marks?

Gas Marks are temperature settings used on gas ovens, primarily in the UK and some European countries. Each mark represents approximately 25°F (14°C) increase. Gas Mark 4 ≈ 350°F (177°C), which is moderate oven temperature. Gas Mark 6 ≈ 400°F (200°C), which is a hot oven.

At what temperature are Fahrenheit and Celsius the same?

-40 degrees! -40°F = -40°C. This is the only point where the two temperature scales intersect. It's extremely cold - much colder than the coldest inhabited places on Earth.

Do I need to convert oven temperatures exactly?

For most home baking, rounding to the nearest 5°C is fine. Ovens typically vary by ±10-25°F anyway. However, for delicate items like soufflés or macarons, use the precise conversion. Always use an oven thermometer to verify your oven's actual temperature.

Why do some recipes say '180°C fan'?

Fan-assisted (convection) ovens circulate hot air, cooking faster and more evenly. They're typically set 15-25°C (25-45°F) lower than conventional ovens. '180°C fan' is equivalent to about 200°C conventional (392°F), which is close to 400°F conventional ovens.
