Oven Temperature Converter Calculator

What is 350°F in Celsius and gas mark?

Oven temperatures convert between Fahrenheit, Celsius, and UK gas mark using standard formulas and a gas-mark lookup table.

**Formula (°F ↔ °C):**

°C = (°F − 32) × 5 ÷ 9

°F = °C × 9 ÷ 5 + 32

**Example — 350°F:**

(350 − 32) × 5 ÷ 9 = **177°C**, **Gas 4**

Fahrenheit, Celsius, and UK gas mark conversion

Exact °F ↔ °C arithmetic plus nearest UK gas mark from a standard baking temperature table.

Formula

°C = round((°F − 32) × 5/9); gas = nearest mark from standard table (Gas 4 ↔ 350°F)

Assumptions

  • US Fahrenheit and metric Celsius for recipe conversion.
  • UK gas marks 1–9 mapped to conventional oven Fahrenheit anchors.
  • Gas mark rounds to the nearest standard mark for in-between °F values.

Limitations

  • Fan/convection ovens may need 20°C (≈25°F) lower than conventional recipes.
  • Oven thermometers vary — verify with an oven thermometer.
  • Not for meat doneness temps — use a food thermometer for internal temperature.

How to use Oven Temperature Converter Calculator

  1. Read recipe temperature

    Note whether the recipe uses °F, °C, or gas mark.

  2. Enter the value

    Type the oven temperature from your recipe.

  3. Select from and to units

    Pick Fahrenheit, Celsius, or gas mark.

  4. Adjust for fan oven

    If using convection, reduce °C by ~20 compared to conventional recipes.

  5. Preheat fully

    Allow the oven to reach temperature before baking.

Match recipe convention

Common mistakes to avoid

Using gas mark in a US oven without conversion

US ovens use **°F only** — convert gas mark to Fahrenheit first.

Ignoring fan-oven adjustment

Reduce **20°C** when a recipe assumes a conventional oven.

Trusting oven dial accuracy

Verify with an **oven thermometer** — many ovens run hot or cold.

Frequently Asked Questions

How do I convert a common baking temperature to Celsius?

Enter **350°F** — the calculator returns **177°C** and **Gas 4** using (°F − 32) × 5 ÷ 9.

What gas mark is 350°F?

**Gas 4** — the standard UK gas mark for 350°F baking.

How do I convert Celsius to Fahrenheit for baking?

°F = °C × 9 ÷ 5 + 32. Example: 180°C → **356°F**.

What is Gas 4 in Fahrenheit?

**350°F** (177°C) in the standard UK gas mark table.

Should I lower temp for a fan oven?

Yes — reduce **~20°C** (or ~25°F) vs conventional recipes unless the recipe says fan.

Oven converter vs general unit converter?

This tool is tuned for **baking oven temps and gas marks** — use it alongside Recipe Scaler for holiday baking.

What temperature for pizza?

Home pizza often **450–500°F** (232–260°C, Gas 8–9); stone ovens go higher.

Why does my cake burn at the converted temp?

Ovens vary — try **25°F lower** or use an oven thermometer to calibrate.

Is 180°C the same as 350°F?

No — 180°C ≈ **356°F** (Gas 4). 350°F is **177°C**.

Can I convert meat roasting temps here?

Yes for oven setting — but always verify **internal meat temperature** with a food thermometer.
