About our cooking
Cooking calculators take the fiddly arithmetic out of the kitchen — scaling a recipe up for a crowd or down for two, converting between cups, grams, ounces and millilitres, and adjusting cooking times when quantities or pan sizes change. Recipes are written for a fixed yield and often in whichever units the author preferred, which leaves home cooks juggling awkward fractions and unfamiliar measures at exactly the moment their hands are full. These tools resolve that in a second, turning a recipe for four into one for ten, or a stubborn cup measure into the grams a kitchen scale wants. Home cooks resize family recipes for gatherings; bakers convert volume to weight for the precision that good pastry demands; meal-preppers batch dishes up cleanly; and anyone following a recipe from another country translates its units without second-guessing. Each tool applies the standard method — a simple ratio for scaling, defined density and unit factors for conversions — and shows its working so you can trust and reproduce the result. The important limitation is that ingredient conversions between volume and weight depend on the ingredient itself: a cup of flour, sugar and butter each weigh different amounts, so these tools use standard reference densities that suit most cooking but may differ slightly from a specific brand or how firmly you pack a measure. Baking rewards weighing over volume for that reason. Treat the figures as reliable starting points, and trust taste, texture and a thermometer for the final call.
Common questions about cooking
How do I scale a recipe up or down?
Multiply every ingredient by a single scaling factor — the new yield divided by the original. To take a recipe for four up to six, multiply each quantity by one and a half. Amounts scale cleanly, but seasoning, cooking time and pan size do not always follow in step: taste and adjust salt and spices, and expect timing to shift when depth or surface area changes. A scaling tool handles the multiplication so you can focus on those judgement calls.
Why should I weigh baking ingredients instead of measuring by volume?
Because volume is unreliable for dry ingredients, especially flour. A cup of flour can vary by a fair margin depending on how firmly it is packed and whether it has settled, which throws off the flour-to-liquid balance that baking depends on. Weighing in grams removes that variability and gives the same result every time. This is why serious baking recipes list weights, and why a conversion tool that turns cups into grams makes your results far more consistent.
Do cooking times change when I scale a recipe?
Often, but not in proportion to the quantity. Doubling a soup barely changes the simmer once it is hot, while a larger roast or a deeper cake needs meaningfully longer to cook through. Timing depends more on thickness, depth and pan size than on total volume, so use the original time as a guide and judge doneness by temperature, colour and texture. A thermometer is the most reliable check whenever you change the batch size.
