Pergallon

Pergallon is a unit of measurement used to express a rate or cost associated with a liquid, most commonly gasoline or milk. It represents the quantity of a substance that can be obtained or the cost incurred for one gallon of that substance. For example, when discussing fuel efficiency, a vehicle's rating might be expressed in miles per gallon, indicating how many miles the car can travel on one gallon of fuel. Similarly, when purchasing liquids in bulk, a price might be quoted per gallon, allowing consumers to compare the cost-effectiveness of different sizes or brands. The concept of "per gallon" is fundamental in various economic and practical contexts where liquids are consumed or traded. It provides a standardized way to quantify value and consumption patterns, facilitating comparisons and decision-making. The unit is widely recognized in countries that use the US customary system of units.
