Kitchen maths, done in the browser.
Every tool runs client-side. Nothing you type is sent anywhere. Each sits beside the guide that explains it.
Unit converter
Converts within volume or within weight. Each result states which cup or spoon it uses.

Oven temperature
Fan-oven adjustment is a convention (~20 °C lower), not an exact rule. Gas marks are the nearest in the table.
Oven temperature
Ovens vary. An oven thermometer tells you what yours really does. Fan adjustment is a convention (about 20 °C), not an exact rule.
Recipe scaler
Seasoning, cooking time and pan size do not scale in a straight line — use judgement.
Recipe scaler
Seasoning, cooking time and pan size do not scale in a straight line — use judgement. Eggs and whole items: round to the nearest whole number.
Baker's percentage
All percentages relative to flour weight (always 100%). The result is a guide, not a guarantee — flour absorbs water differently by brand and humidity.
Cups to grams
Approximate. Values are based on spooned-and-levelled cups and vary by packing method and brand. For baking, weigh.

Assumption: Spooned and levelled
Cup-to-gram weights vary by packing method and brand. For baking precision, use a scale.
Kitchen timer
Keeps correct time when the tab is in the background. Always use a thermometer to test doneness — time is a guide, not a guarantee.
