Estimate the total pounds of seafood to buy for a meal based on guest count and the planned serving size per person. This is a simple planning estimate for edible seafood portions.
Estimate the total pounds of peeled, edible shrimp to prepare by multiplying the number of guests by the planned shrimp serving per person. Choose a serving size that fits the meal, then round up for shopping if needed.
Estimate the amount of uncooked sushi rice to prepare based on guest count and serving style. The estimate uses a fixed per-person portion and does not account for other menu items or individual appetite.
Estimate the cooked lobster meat available from whole lobsters using the number of lobsters, their average whole weight, and an assumed meat-yield percentage. This is a planning estimate; actual yield varies by lobster and preparation.
Estimate the water volume in liters from a rectangular pot’s interior length, width, and water depth, using centimeters. This geometric estimate assumes straight vertical sides and does not account for the lobster, a steaming rack, or other contents.
Convert a weight in ounces to its equivalent in grams using the standard avoirdupois conversion factor.
Estimate the amount of food to prepare per person by dividing the total batch weight by the number of servings. Enter the batch weight and serving count to get an average portion weight.
Scale a recipe by comparing the number of servings you want with the recipe’s original servings. The result shows the multiplier to apply to each ingredient amount.
Estimate calories, protein, carbohydrates, fat, and fiber per serving by entering each nutrient total for the full recipe and the number of servings. This worksheet divides recipe totals evenly and does not analyze ingredients or account for cooking-related changes.
Estimate the water needed for a chosen amount of rice using your preferred water-to-rice ratio. Enter rice and water in the same volume unit, such as cups.
Calculate the amount of sanitizer concentrate and water needed to prepare a target volume at a chosen dilution. This arithmetic worksheet assumes the label dilution is expressed as parts concentrate per parts water and does not replace the product label or required concentration testing.
Estimate the total seafood boil weight from the number of guests, seafood portion per guest, and extra serving allowance. This is a food-planning estimate, not a cooking-time or food-safety calculator.
Estimate the pot capacity in liters by multiplying seafood mass by the selected pot capacity per kilogram. This is a planning estimate that does not account for water, other ingredients, or required headspace.
Estimate the kilograms of ice needed for a seafood cooler by multiplying its volume in liters by a chosen ice-per-liter planning rate. This simple estimate does not account for temperature, cooler insulation, opening frequency, or trip duration.
Estimate the time required to cool a seafood batch by dividing its mass by a supplied cooling rate. This simple model assumes a steady rate and does not verify food-safe temperatures or handling procedures.
Estimate the ingredient cost per serving for a seafood meal by combining seafood and other ingredient costs, then dividing by the number of servings. Enter costs in the same currency.
Estimate the freezer volume needed for a set number of seafood packages using the stated volume per package. Enter the count and volume in liters. The estimate assumes every package has the same volume and does not include extra room for airflow or irregular packing.
Estimate the combined volume occupied by packaged seafood in a freezer. Enter the number of packages and the measured volume of one package in cubic centimeters. The estimate assumes every package has the same volume and adds package volumes without accounting for gaps, shelves, airflow, or freezer shape.
Estimate the mass of ice to use for chilling seafood based on seafood mass and a chosen ice-to-seafood ratio. This simple planning estimate assumes the selected ratio accounts for your handling conditions and does not replace food-safety guidance.
Estimate the combined geometric volume of seafood meal containers in liters from their count and internal dimensions. The calculation assumes each container is a rectangular box and uses centimeters for all dimensions.

Estimate the starting water volume for a shellfish boil from the pot's usable capacity and the space reserved for seafood, vegetables, and other ingredients. This planning estimate assumes water and ingredients share the pot and does not account for evaporation or a cooking method that requires a different fill level.
Estimate the grams of seasoning to add based on the volume of water and your chosen seasoning rate in grams per liter. This is a transparent scaling calculation, so use the seasoning rate recommended by your recipe or product label.
Estimate the water volume needed to fill a rectangular sous vide container from its inside length, inside width, and water depth.
