Salt & Brine Calculators
Choose a calculator for salt per litre, equilibrium brine, fish brine, percentages, dry salting or recipe scaling.
Salt per litre of water
Calculate grams of salt per litre for a recipe percentage. Compare water-based and total-solution definitions with worked examples.
CalculatorEquilibrium brine calculator
Calculate plain salt from combined food and water weight. See the formula, denominator and a worked food-plus-water example.
CalculatorFish brine calculator
Calculate plain salt for fish brine using your recipe percentage. Compare water and solution weight; understand initial brine versus finished-fish salinity.
CalculatorBrine percentage calculator
Find a brine percentage from known salt and water amounts. Compare salt-to-water with salt-to-solution concentration.
CalculatorDry salting calculator
Calculate plain salt as a percentage of food weight, with zero added water. Enter the percentage specified by your recipe.
CalculatorBrine recipe scaling calculator
Scale the water, salt and optional food quantities in a brine recipe by one factor while preserving the ingredient ratio.
Know your percentage basis
Use the denominator and plain-salt amount from your recipe. Worked examples explain the arithmetic; they do not prescribe a preservation process.
