One part per gallon (PPG) refers to a concentration measurement that indicates how much of a substance is present in one gallon of liquid. It can be expressed as a fraction, where one part represents a specific volume of the substance compared to the total volume of one gallon (128 ounces). For example, 1 PPG means one ounce of a substance is mixed with one gallon of water. This measurement is commonly used in various fields, such as chemistry and environmental science, to specify dilute solutions or mixtures.
