Calculators
Planning tools related to creative home cooking, with visible assumptions and clearly explained results.
Convert a conventional oven recipe's temperature and cooking time to an estimated air fryer setting. This worksheet applies a user-selected temperature reduction and time multiplier to the oven instructions. Results are estimates; check food for doneness and follow appliance and food-safety guidance.
Convert ingredient weights into baker's percentages using flour weight as the 100% reference, and calculate ingredient weights from a target flour amount.
Convert a measured baking quantity between common volume and weight units. Volume-to-weight conversions use an approximate ingredient density, so choose the ingredient that best matches your recipe.
Use your own inputs to calculate the result for bread dough batch.
Calculate baker’s hydration by comparing the water weight in your dough with the total flour weight. Enter weights in grams to see the water percentage used in your formula.
Estimate a rectangular bread pan’s internal volume in cubic inches by multiplying its length, width, and height. Measure the inside dimensions; the result is a geometric capacity estimate, not a dough-fill recommendation.
Calculate the salt and water amounts for a target salt-to-water brine concentration. Enter water volume and target salt percentage by water weight. This estimate assumes 1 liter of water weighs 1 kilogram and does not account for the volume added by salt.
Convert a measured sucrose solution concentration from grams of sugar and total solution mass into degrees Brix by mass. This arithmetic estimate assumes the solution contains only sucrose and water.
Convert a measured amount of butter between grams, ounces, tablespoons, and cups using standard kitchen equivalents. Choose the starting unit and the unit you need for your recipe.
Scale one cake ingredient to a new batch size by multiplying its original amount by the target servings and dividing by the original servings. Enter all ingredient amounts in grams.
Estimate a cake's selling price from ingredient cost, labor, overhead, and your target profit margin. This simple worksheet assumes those costs are entered per cake and applies the margin to the final price.
Estimate how many equal-area servings a rectangular cake pan can provide from its dimensions and the area allotted to each serving. The result is a fractional area estimate, not a cutting plan.
Convert a conventional oven temperature to an approximate convection oven setting by reducing the set temperature by a chosen number of degrees. This estimates oven settings only and does not adjust cooking time.
Convert a cooking quantity between common volume units using their standard US customary relationships. Enter an amount and choose the unit to convert from and to.
Estimate a planning time by scaling a known recipe's cooking time in direct proportion to the food's weight, with an optional thickness adjustment. This simplified worksheet assumes the same food, cooking method, equipment, and starting conditions; it does not determine whether food is safely cooked.
Convert a volume measured in cups to milliliters using the US customary cup standard of 236.5882365 milliliters per cup.
Estimate the volume of cooked beans from dry beans using an adjustable yield multiplier. The estimate assumes the beans are sorted, soaked or prepared as directed, and cooked until tender.
Estimate the cooked weight of dry pasta using a yield multiplier you provide. The result is an arithmetic estimate, since pasta shape, cooking time, and draining affect the final weight.
Estimate cooked rice volume from the amount of dry rice using an approximate 3-to-1 cooked-to-dry volume ratio. Results are estimates and vary with rice variety and cooking method.
Convert a temperature in degrees Fahrenheit to degrees Celsius using the standard formula.
Calculate the salt needed for a water-based fermentation brine from your water volume and target salt percentage. This worksheet assumes the percentage is salt by weight relative to water weight and treats 1 mL of water as approximately 1 g.
Convert a measured weight of all-purpose flour in grams to an approximate volume in US cups using a standard reference weight of 120 grams per cup.
Estimate ingredient cost per serving from the total ingredient cost and the number of servings. Enter amounts in the same currency and use the full recipe yield.
Convert a measured weight in grams to an approximate US cup amount using the selected ingredient's standard kitchen weight per cup.
Calculate an ingredient's cost per ounce from the package price and the package weight in ounces. Enter the price you paid and the net ingredient weight shown on the package.
Estimate the amount of a replacement ingredient needed from the amount called for and a chosen substitution ratio. This simple quantity model does not predict changes in flavor, texture, or cooking behavior.
Estimate the amount of each prepared ingredient to portion for a chosen number of meals, using the recipe yield and serving size you enter.
Convert a weight in avoirdupois ounces to grams using the standard factor of 28.349523125 grams per ounce.
Convert an oven temperature between Fahrenheit and Celsius using the standard temperature conversion formula. Enter a value in either scale to see the equivalent temperature in the other scale.
Estimate the total amount of dry pasta to cook from the number of diners and the dry pasta serving size per person. This uses one consistent portion assumption and does not adjust for appetite or pasta shape.
Calculate the salt and water amounts for a simple pickling brine from your chosen water volume and salt concentration. This estimates brine proportions only and does not validate a preservation method or food safety.
Estimate the ingredient cost of each serving by dividing the total recipe ingredient cost by the number of portions. This estimate covers ingredient costs only and does not include labor, packaging, utilities, or overhead.
Scale a recipe's ingredient amounts to match the number of portions you need. Enter the recipe yield and the desired portions to see the multiplier and adjusted amount for a selected ingredient.
Estimate how many batch-sized portions fit within a pressure cooker’s usable capacity, based on the pot volume and the fraction you plan to fill. This simple volume estimate does not account for ingredient expansion, liquid requirements, or recipe-specific fill limits.
Scale ingredient amounts by comparing the number of servings in the original recipe with your desired servings. The result shows the multiplier to apply to each ingredient.
Divide a recipe's total amount of a selected nutrient by the number of servings to estimate the amount per serving. Enter totals from ingredient labels or another nutrition source; this calculator does not identify foods or look up nutrient data.
Estimate the water to use for a batch of rice by multiplying the dry rice amount by a selected water-to-rice ratio. Choose a ratio that matches your rice and cooking method, then measure both ingredients in the same unit.
Calculate how much sauce to use for a given amount of pasta by applying your chosen sauce-to-pasta ratio. Enter both quantities in the same unit, such as grams, ounces, or cups.
Calculate the salt amount for a batch of sauerkraut from the weight of prepared cabbage and your chosen salt percentage. This simple weight-based guide uses cabbage weight only and does not include other vegetables or added liquid.
Estimate how many portions fit in one slow cooker batch from the cooker’s capacity, chosen fill fraction, and volume allocated per serving.
Estimate how much soup to prepare by multiplying the planned number of servings by the portion size per person.
Estimate the finished volume of soup from its starting liquid and added broth or water, then account for liquid lost during cooking.
Calculate total dough hydration as a baker’s percentage using the flour and water in your recipe, including the flour and water contributed by your sourdough starter.
Calculate the flour and water to add to a sourdough starter by weight, using a feeding ratio expressed as parts starter, flour, and water.
Convert a measured number of tablespoons into cups using the standard US kitchen conversion of 16 tablespoons per cup.
Convert a measured amount in tablespoons to an estimated weight in grams by choosing the ingredient. The result uses a typical ingredient density, so weighing the ingredient is best when precision matters.
Convert a measured volume in teaspoons to milliliters using the standard kitchen conversion of 1 US teaspoon to 4.92892 milliliters.
Compare the cost of pantry goods by converting each package price to a common unit. Enter the price and quantity for two products, then choose the unit used for both quantities.
Calculate the water to add to a measured amount of vinegar to reach a chosen lower acidity. This simple volume calculation assumes the vinegar’s labeled acidity is accurate and ignores small volume changes during mixing.
Convert a recipe’s yeast amount between active dry, instant, and fresh yeast using common baking equivalencies. Enter the amount and unit, then select the yeast type used in the recipe and the type you have.
