Let the tools do the kitchen maths.
Every calculator runs in your browser — nothing you type leaves the page. Each sits beside the guide that explains the why.

Oven temperatures at a glance
The conventional temperatures every recipe means when it says "moderate" or "hot". Fan ovens run roughly 20 °C cooler — reduce accordingly.
Fan-oven equivalent: about 20 °C lower than the conventional temperature shown. Ovens vary — an oven thermometer is the most reliable check.
| Heat | °C | °F | Gas mark | |
|---|---|---|---|---|
| Very low | 120 | 250 | 0.5 | |
| Low | 150 | 300 | 2 | |
| Moderate | 180 | 350 | 4 | |
| Hot | 200 | 400 | 6 | |
| Very hot | 220 | 425 | 7 | |
| Maximum | 240 | 475 | 9 |
Questions about the kitchen tools
- No account is needed. All six tools are fully browser-based — once the page loads they run offline. Nothing you enter is stored or sent to a server.
- The converter defaults to the US legal cup (240 ml). It also offers the US customary cup (236.6 ml), the metric cup (250 ml) and the Australian tablespoon (20 ml). The result always states which cup was used.
- No. Reducing by ~20 °C (or one Gas Mark) for fan ovens is a widely accepted convention, not a regulated standard. Actual results vary by oven model. The BBC Good Food oven guide and most UK cookbooks follow the same convention.
- Volume measures of dry ingredients depend on how the ingredient is packed. The same US cup of flour can weigh anywhere from 120 g (sifted) to 150 g (scooped). For baking accuracy, weigh ingredients. The King Arthur weight chart is a useful additional reference.
- In baker's percentages, every ingredient is expressed as a percentage of the total flour weight, which is always 100%. A 70% hydration dough means 70 g of water per 100 g of flour. This system makes scaling any recipe trivial. The Fresh Loaf handbook covers it in depth.
