A common method to determine ounces per gallon is to take 128 and divide it by the ratio number. For example a dilution rate that is 1:128, would be calculated like this, 128÷256 =.5 ounces per gallon or 1000ml/256 = 4ml/ litre. The proper way to show a dilution is how many parts of the concentrated product are to bediluted to how many parts of water. As an example, 1-ounce to a gallon (128-ounces) would be 1:128, not 128:1.
Some of the more common ratios are provided in the table below:

The total amount of solution that a container of product makes is commonly referred to as the yield. Metric calculations such as liters can be calculated, you just need to convert the metric figures to gallons or ounces prior to starting. Common metric volume measurements and their English equivalents are listed below:
