Free kitchen tools for real cooking problems.
Scale a recipe, convert cups to grams, resize a baking recipe for another pan, work out food for a crowd, find a sensible ingredient substitute, calculate fermentation salt, untangle dough hydration — or let Potluck decide what to cook tonight. No account, no ads — just useful cooking tools made by a chef.
Recipe Scaler
Paste an ingredient list, change the serving count and get scaled quantities instantly — with chef notes for the bits that do not obey multiplication.
Scale a recipe →ConversionsCooking Measurement Converter
Convert cups, grams, ounces, ml and temperatures — or paste a whole ingredient list and flip it between US and metric.
Convert measurements →BakingBaking Pan Converter
Switch a cake, brownie or tray-bake recipe to the pan you actually own — with the batter multiplier, depth change and optional ingredient scaling.
Convert a pan size →PlanningFood Portion Planner
Work out how much pasta, rice, meat, potatoes and more to buy for adults, kids, buffets, big appetites and leftovers.
Plan food for a crowd →IngredientsIngredient Substitution Finder
Find practical swaps for missing ingredients, with the ratio, what changes and when the substitute is a bad idea.
Find a substitute →FermentationFermentation Brine Calculator
Calculate salt by total vegetable + water weight or by water-only brine percentage, without mixing up the two conventions.
Calculate brine salt →Dinner decisionsPotluck Random Dinner Generator
Spin once and get a real recipe to cook tonight — not just a random food name. Free in the browser, no signup and no endless feed.
Spin for dinner →Bread & pizzaBaker’s Percentage & Hydration
Calculate true dough hydration, account for flour and water inside starter, and scale a bread or pizza formula to the batch you need.
Calculate dough percentages →Kitchen judgement first. Tool second.
These are small utilities built around the awkward bits that actually come up while cooking — from kitchen maths to the surprisingly hard question of what to make for dinner. Where a number is only an estimate, the tool says so instead of pretending the kitchen is a spreadsheet.
The measurement converter also uses the same growing ingredient-conversion library as the Savor app, so improvements to Savor’s cooking data improve the free web tool too.

We’ll keep adding tools when they solve a real cooking problem — not just to manufacture another calculator page.
