Baking-pan maths as an API, computed locally and deterministically — the area and scale-factor numbers a baker resizes a recipe between pans with. The trick everyone gets wrong is that a recipe scales by the pan’s AREA, not its diameter, so a 10-inch round holds far more batter than a 9-inch. The area endpoint gives the surface area of any pan — round and springform as π/4·d², square as s², rectangle as length × width, and bundt or tube pans as the ring (the outer circle minus the centre hole) — so a 9-inch round is 63.6 in², an 8-inch square 64 and a 9×13 is 117; add a depth and it returns the volume in cubic inches and cups. The convert endpoint gives the scale factor to move a recipe from one pan to another, factor = target area ÷ source area: a 9-inch round to a 9×13 is ×1.84, and two 8-inch rounds really do equal one 9×13. Pass an ingredient amount and it scales it for you, with a note to keep the batter depth similar and adjust the bake time. Everything is computed locally and deterministically, so it is instant and private. Ideal for baking, recipe, meal-prep and kitchen app developers, recipe-scaling and substitution tools, and culinary software. Pure local computation — no key, no third-party service, instant. Inches. Live, nothing stored. 2 compute endpoints. For ingredient unit conversion use a cooking API.

Pizza and bread dough maths as an API, built on baker's percentages — where the flour is always 100% and every other ingredient is expressed as a percentage of the flour weight. The dough endpoint computes a full recipe in grams (flour, water, salt, yeast, oil and sugar) from a target quantity — either a number of dough balls and a ball weight, a total dough weight, or a flour weight — together with a hydration and salt/yeast percentages, or a built-in style preset (Neapolitan, New York, Detroit, Sicilian, focaccia, ciabatta, baguette, sandwich). The hydration endpoint converts between flour, water and hydration percentage and classifies the dough from stiff to extremely wet. The presets endpoint returns the common dough styles as baker's percentages with typical ball weights. Everything is computed locally and deterministically, so it is instant and private. The yeast figure is instant dry yeast (use roughly three times as much fresh). Ideal for recipe and baking apps, pizzeria and bakery tools, meal-planning and kitchen-scale integrations, and food blogs. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is dough formulation by baker's percentage; for ingredient volume-to-weight and oven-temperature conversion use a cooking API.

Recipe and kitchen conversions as an API. Convert between volume units (teaspoon, tablespoon, cup, fl-oz, ml, litre, pint, quart, gallon) and between mass units (gram, kilogram, ounce, pound) — and, crucially, between volume and mass for a specific ingredient using its density, so 1 cup of all-purpose flour ≈ 125 g, 1 cup of granulated sugar ≈ 200 g and 1 cup of water ≈ 237 g. 30 common ingredients are built in (flours, sugars, butter, oils, honey, rice, oats, cocoa, cornstarch and more), each with its grams-per-cup. Perfect for recipe apps, scaling and "metric vs cups" conversion, shopping lists and meal-prep tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from general physical unit conversion, which has no ingredient densities.
