Kitchen & Cooking
Every kitchen & cooking calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
19 calculators in this section
- Air Fryer Conversion CalculatorConvert an oven recipe to air fryer settings, and back, with each manufacturer's own published rule rather than a blog's average — and with the arithmetic mistake in the familiar “25 °F, about 20 °C” shorthand shown rather than repeated. A 25 Fahrenheit-degree drop is 13.9 °C. Time is an estimate here; internal temperature decides.
- Brine Calculator (Equilibrium, Wet and Dry)How much salt for a brine, on all three bases that are actually used — equilibrium brining as a percentage of meat plus water, traditional brining as a percentage of the water, and dry brining as a percentage of the meat. The same “1.5%” is three different doses. Answered in grams first, because salt type changes the volume by a factor of two and not the mass. Nitrite curing salts are refused.
- Butter Converter (Sticks, Cups, Tablespoons, Grams)Convert butter between US sticks, cups, tablespoons, grams, ounces and the European 250 g block, in any direction, with the wrapper markings explained and an honest account of what melting does to a measured tablespoon.
- Can and Jar Size Converter (#10, #303, #2½)Turn the old US commercial can numbers — No. 1, No. 2, No. 2½, No. 300, No. 303, No. 10 and the rest — into millilitres, fluid ounces, cups, net weight and drained weight, both ways, with the distinction between the three that makes substitution go wrong.
- Chocolate and Cocoa ConverterSwap between unsweetened chocolate, cocoa powder, bittersweet bars and chips by mass balance on cocoa solids and cocoa butter — with the classic 3-tablespoon rule derived from the legal fat bands rather than quoted, and the Dutch-process leavening problem stated as the chemistry it is.
- Coffee Brew Ratio CalculatorDose, water and yield for pour-over, drip, French press, immersion, AeroPress, cold brew and espresso — with the water the wet grounds keep taken out, so a 1:16 brew is shown as the 1:14 drink it actually is. Espresso handled as its own thing, because its ratio is dose to liquid out.
- Cream Fat Content ConverterWhat “cream” means in the US, UK, France, Australia and India, with the legal minima quoted where they are legal and named as conventions where they are not — plus the mass balance that mixes one cream into another, and an honest account of why butter and milk will not whip.
- Cups to Grams Converter (by Ingredient)Convert cups, tablespoons, teaspoons and millilitres to grams and ounces for 26 named ingredients, in both directions, using published densities from USDA FoodData Central and King Arthur Baking — with the source of every number on the page, and the 120 g to 160 g spread for a cup of flour stated rather than hidden.
- Dough Hydration Calculator (Baker’s Percentage)Baker's percentage in both directions — flour weight to every other weight, and a target total dough weight back to the flour — with a sourdough starter's flour and water split out, and OVERALL against DOUGH hydration printed as two separate numbers with both named. That split is the single biggest disagreement between published dough calculators, and the EU's legal Neapolitan pizza formula turns out to be 55.6% hydration, not 60.
- Meat Cooking Temperature Converter (°C, °F, Doneness)Internal temperatures for meat by food and by doneness, in °C and °F both ways, with the USDA FSIS safe minimums reproduced exactly and kept separate from the culinary doneness scale — and a carryover-cooking estimate that says what drives it and how uncertain it is.
- Oven Temperature Converter (°C, °F, Gas, Fan)Convert between °C, °F, gas mark and a fan oven setting in any direction, with the exact gas-mark definition, the 20 °C fan convention in both directions, the descriptive names older recipes use, and an honest account of how far published Celsius tables sit from the exact conversion.
- Recipe Scaling Calculator (Servings or Tin Size)Scale a recipe by servings or by tin size, with the area arithmetic shown, the new batter depth, a physics-based estimate of what happens to the baking time, and an explicit list of what does not scale — eggs, leavening, salt and time.
- Rice Water Ratio Calculator (By Type and Method)Water per cup of rice for twelve kinds of rice and five cooking methods, with the absorbed water computed from USDA composition and the boiled-away water separated out — which is why no two published ratios agree, and why the ratio falls as the pan fills.
- Roast Cooking Time CalculatorRoasting time by weight from USDA FSIS's own charts, reproduced in full because they are US Government work — and re-read as the scaling law the physics asks for, because FSIS's own turkey timetable implies 17.3 minutes per pound at 10 lb and 13.0 at 22 lb. A joint twice the weight does not take twice as long. The thermometer, not the clock, decides when it is done.
- Salt Conversion Calculator (Table, Kosher, Sea)Convert between table salt, Morton coarse kosher, Diamond Crystal kosher and fine sea salt by volume and by weight, in both directions, from the makers' own published densities — and see why weighing salt makes the problem vanish. Nitrite curing salts are not interchangeable with table salt at any ratio.
- Spoon Measure ConverterTablespoons, teaspoons and dessertspoons between the US customary, US legal, metric, modern UK, historic imperial and Australian conventions — built around the two facts that matter: the Australian tablespoon is 20 mL and four teaspoons, and the old imperial tablespoon was smaller than today's, not larger.
- Sugar Substitute Converter (Honey, Stevia, Erythritol)Swap granulated sugar for honey, maple, agave, molasses, brown and coconut sugar, stevia, erythritol, xylitol, allulose, sucralose or monk fruit — by weight and by volume, with the liquid, acid, oven and missing-bulk adjustments each one needs, and the uses where it does not work at all.
- US, UK and Metric Kitchen Measures ConverterConvert every common kitchen volume measure between US customary, imperial, metric and Australian conventions, in any direction, with each unit's system named: a US pint is 473 mL and an imperial pint 568 mL, and an Australian tablespoon is 20 mL against 15 mL everywhere else.
- Yeast Conversion Calculator (Fresh, Active Dry, Instant)Convert between fresh compressed yeast, active dry yeast and instant yeast by weight or by the spoon, in both directions, using the makers' own published equivalences and the 2.4 to 2.7 spread between them — with what else changes: proofing, granule size and shelf life.
