Frequently Asked Questions
Common questions about the free online dilution ratio calculator.
It means one part product mixed with ten parts water or solvent, giving eleven parts in total
and a product strength near 9.1 percent.
Add the parts together, divide the total volume by that sum, then measure out one share for
each part of the ratio.
The dilution factor is the total number of parts divided by the parts of product, so a 1 to
10 mix has a factor of 11.
Yes. Switch the mode to the product amount and the tool calculates how much water or solvent
to add to what you measured.
Usually add the concentrate to the water rather than water to the concentrate, because that
is safer and mixes more evenly.
Measure one part of the solution and ten parts of water in the same unit, which gives roughly
a 0.9 percent working strength.
