How to calculate
Solve salt mass against the explicitly selected denominator.
Water basis: s=pw; solution basis: s=pw/(1−p); whole basis: s=p(w+food)/(1−p)
Worked example
At 2%, 1000 g water requires 20 g salt on water basis, 20.408163 g on final-solution basis, or 30.612245 g with 500 g food on whole-mixture basis.
Assumptions and input details
The percentage is a user-entered arithmetic scenario. Salt already present, absorption and aqueous salt concentration inside food are not inferred. This does not establish preservation safety, fermentation conditions, a validated recipe or a recommended salt level.
Unit definitions
Unit selection is independent of language. Each selector contains only units for its physical quantity. Calculations use defined base units internally.
The 19 mass definitions distinguish avoirdupois and troy measures, metric and regional measures. Japanese kin is 600 g; mainland Chinese shijin is 500 g.
Regional measures are not interchangeable merely because their names look similar. This is a documented selection, not a claim to include every historical unit.

Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
