How do I convert Celsius to Fahrenheit for baking?

Use the formula °F = °C × 9/5 + 32. So 180 °C becomes 180 × 1.8 + 32 = 356 °F. The converter does this instantly for you.

What is 180 °C in Gas Mark?

180 °C corresponds to Gas Mark 4 on the standard UK table. This is the classic moderate baking temperature used for most cakes and biscuits.

What does Gas Mark 6 mean in Celsius and Fahrenheit?

Gas Mark 6 is 200 °C (392 °F) — a moderately hot oven, suitable for roasting chicken, baking pizza bases, or cooking jacket potatoes.

Why does Kelvin matter in cooking?

Kelvin is mainly used by food scientists and sous-vide engineers who need absolute thermodynamic calculations. For everyday cooking Celsius or Fahrenheit is sufficient, but the converter includes Kelvin for completeness. K = °C + 273.15.

Are UK and US oven temperatures the same?

The Celsius and Fahrenheit scales are universal. Gas marks, however, are a UK/Irish convention and not used in North America or most of Europe. US recipes almost always specify Fahrenheit; UK recipes often give Celsius and Gas Mark together.

My recipe says 350 °F — what is that in Celsius?

350 °F converts to (350 − 32) × 5/9 = 176.7 °C, which rounds to 175–180 °C depending on your oven. This is a standard moderate-heat temperature for baking cakes, muffins and cookies.

Cooking Temperature Converter

Whether you are following a UK recipe that lists oven settings in Gas Marks, an American cookbook written in Fahrenheit, or a scientific sous-vide guide that works in Kelvin, this cooking temperature converter handles every combination instantly. Type once, get all four scales simultaneously, with the correct conversion formula shown as working underneath.

How it works

Every temperature conversion flows through the Celsius scale as a neutral pivot:

°C to °F: multiply by 9/5, then add 32. The inverse is (°F − 32) × 5/9.
°C to Kelvin: add 273.15. Kelvin is the SI unit of thermodynamic temperature; 0 K is absolute zero, so cooking temperatures sit comfortably in the 400–550 K range.
°C to UK Gas Mark: looked up from the empirical table published by UK gas appliance manufacturers. Gas marks are not a linear scale — they were calibrated by testing real thermostats on domestic ovens, so the spacing between marks is slightly uneven. The converter interpolates linearly between adjacent table entries for non-integer input.

The tool also reads the temperature description (Very low, Moderate, Hot, etc.) from a lookup table to give you an instant culinary context clue.

Worked example

Suppose a Victoria sponge recipe says Gas Mark 4. The UK table maps Gas 4 → 180 °C. Applying the formula:

°F = 180 × 9/5 + 32 = 324 + 32 = 356 °F
K = 180 + 273.15 = 453.15 K
Description: Moderate — the classic moderate-bake setting used for most cakes, biscuits and tray bakes.

Now suppose a US banana-bread recipe calls for 350 °F:

°C = (350 − 32) × 5/9 = 318 × 0.5556 = 176.7 °C (round to 175–180 °C)
Gas Mark ≈ 4 (interpolated)
Description: Moderate — same oven, different notation.

Common task	°C	°F	Gas Mark
Slow-cook / confit	140–150	284–302	1–2
Bread, sponge cake	180	356	4
Roasting vegetables	200	392	6
Crispy roast potatoes	220	428	7
Pizza, bread crust	240–250	464–482	9–10

Formula note

The Celsius–Fahrenheit formula is an exact, linear relationship defined by two fixed points: water freezes at 0 °C / 32 °F and boils at 100 °C / 212 °F. Kelvin uses the same degree size as Celsius but starts at absolute zero (−273.15 °C). Gas Marks have no single equation — they originate from a 1930s standardisation of UK domestic gas cooker thermostats and are specified by table only.
