5 ounces per gallon –īoth ways mean the same thing – you would mix one part of the product to 256 parts water. Dilution ratios can also be expressed in terms of ounces per gallon such as. Our ratio number and by plugging it into our formula, we can determine how many ounces per gallon of product is needed.Ģ. Now let’s plug in some numbers! For example, a product that has a dilution ratio of 1:256 would be calculated like this:
If a dilution ratio is expressed in this way, you will have to calculateĪ common method to determine ounces per gallon is to take 128 (because that’s how many ounces are in a gallon) and divide it by the ratio number.
Typically, you’ll see dilution ratios expressed as 1 to a given number such as 1:256. Dilution ratios are expressed in two ways:ġ.
