What is an Oven Temperature Converter?

It translates an oven setting between the systems recipes use around the world — Celsius, Fahrenheit, and the UK gas mark — and derives the fan-oven equivalent by subtracting 20°C. One number in, every setting out.

Reach for it when a recipe is written for a different country's oven, when you're switching between a conventional and a fan oven, or when you just want to sanity-check the dial. For the most reliable bakes, pair it with an oven thermometer — home ovens rarely hit their stated temperature exactly.

❓ Frequently Asked Questions

How do I convert Celsius to Fahrenheit for the oven?

Multiply the Celsius figure by 9/5 and add 32. So 180°C becomes 356°F. This tool does it instantly and also shows the equivalent gas mark and fan-oven setting, so a recipe in any of those systems is easy to follow.

What is a fan (convection) oven setting, and why is it lower?

A fan oven circulates hot air, so it cooks faster and more evenly than a conventional oven at the same dial reading. The standard rule is to set a fan oven about 20°C below the conventional Celsius temperature — so 180°C conventional becomes roughly 160°C fan. Always watch your bake, as fan strength varies by model.

What does gas mark mean?

Gas mark is the UK scale for gas ovens, running from 1 (coolest, about 140°C) up to 9 (hottest, about 240°C). Gas mark 4 is roughly 180°C / 350°F — the classic 'moderate' oven for cakes and many bakes. This converter maps between gas mark and both temperature scales.

Why does my oven not match the dial?

Home ovens are often out by 10–20°C, and hot spots are common. The reliable fix is an inexpensive oven thermometer placed in the centre — check the real temperature once the oven says it's preheated, and adjust the dial to match the temperature your recipe wants.
