- Exact hardness category
- soft
- Exact soil category
- normal
- Dry laundry mass (kg)
- 4
- Entered-label dose (mL)
- 50
- Selected label load limit (kg)
- 6
- Dose divided by actual load (mL/kg)
- 12.5

Calculation method
Calculation method
Entered-label dose (mL)
Choose matching hardness and soil rows, then the lowest entered load limit at least as large as the actual mass. Use the supplied dose without interpolation.
Selected label load limit (kg)
The selected row’s maximum load.
Dose divided by actual load (mL/kg)
Selected dose / actual mass; descriptive only, not a scaling instruction.

- A lookup in your entered product label table, with exact category matches and no extrapolation. It does not select a detergent, interpret local water chemistry or invent manufacturer dosing rules.
