Calculation method
Calculation method
Observed water parts per concentrate part
Measured water / measured concentrate.
Observed concentrate share (%)
100 × concentrate / (concentrate + water).
Ratio deviation from label (%)
100 × (observed water ratio − label water ratio) / label water ratio.
Symbols and units
- a
- Measured concentrate delivery (mL)
- b
- Measured water delivery (mL)
- c
- Label water parts per concentrate part
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Measurement comparison only. Positive deviation means more water per concentrate part than the supplied label ratio. It does not infer chemical strength or recommend changing the manufacturer’s dilution.
