Dilution Ratio at 36% stock concentration: a worked example

Suppose stock concentration falls to 36%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate dilution ratio from starting concentrate, target concentration, and unit conversion.

The inputs for this scenario

  • Stock (starting) concentration: 36 % (the input this scenario stresses; the baseline uses 50)
  • Desired working concentration: 12.5 % (held at the documented default)
  • Concentration basis conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dilution ratio = starting concentration ÷ target concentration × conversion factor.
  • required dilution ratio works out to 2.88 x at these inputs, and this is the headline figure for the scenario.
  • raw concentration ratio works out to 2.88 value at these inputs.
  • basis conversion factor works out to 1 x at these inputs.
  • target concentration works out to 12.5 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where stock concentration sits at 50% and the headline result is 4 x, this scenario comes in 28% below the baseline at 2.88 x.
  • It computes the dilution ratio, the total parts of solution per part of concentrate, from starting and target concentrations with an optional basis correction. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • required dilution ratio: 2.88 x (headline result)
  • raw concentration ratio: 2.88 value
  • basis conversion factor: 1 x
  • target concentration: 12.5 value

Run it with your numbers

  • To rerun this with your own numbers, open the live Dilution Ratio calculator, set stock concentration to your actual value, and adjust the remaining inputs to match your operation.
