Two-Part Mix Ratio with part a resin amount of 50 g or ml: a worked example

Suppose part a resin amount falls to 50 g or ml. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the mix ratio between resin and hardener after applying the required supplier conversion factor.

The inputs for this scenario

  • Part A resin amount: 50 g or ml (the input this scenario stresses; the baseline uses 100)
  • Part B hardener amount: 25 g or ml (held at the documented default)
  • Supplier mix-ratio conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw mix ratio = Part A resin amount รท Part B hardener amount.
  • Adjusted Part A:Part B ratio works out to 2 x at these inputs, and this is the headline figure for the scenario.
  • Raw resin-to-hardener ratio works out to 2 x at these inputs.
  • Supplier conversion factor works out to 1 x at these inputs.
  • Part B hardener amount works out to 25 g or ml at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where part a resin amount sits at 100 g or ml and the headline result is 4 x, this scenario comes in 50% below the baseline at 2 x.
  • It computes the raw Part A to Part B ratio from your two amounts and then the adjusted ratio after applying the supplier conversion factor. 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

  • Adjusted Part A:Part B ratio: 2 x (headline result)
  • Raw resin-to-hardener ratio: 2 x
  • Supplier conversion factor: 1 x
  • Part B hardener amount: 25 g or ml
