Definition of grain/gallon (UK) unit

Grain per gallon (UK) is a concentration unit expressing one grain of dissolved substance in one British imperial gallon of solution. One grain equals 64.79891 milligrams; one UK gallon equals 4.54609 litres.

History of grain/gallon (UK) unit

The grain is an ancient mass unit, traditionally associated with the weight of a barleycorn and later standardized in English measurement. The British imperial gallon was defined by the Weights and Measures Act of 1824 as the volume occupied by ten pounds of water under specified conditions. Combining these units produced grain per imperial gallon, especially useful in Britain for reporting minerals, salts, and water hardness. Although metric units gradually replaced it, the expression remained familiar in engineering, brewing, and water-treatment records, particularly before international SI adoption.

Applications of grain/gallon (UK) unit

Today, grain per UK gallon may appear in historical water-quality data, British engineering documents, brewing references, and legacy treatment specifications. It can describe dissolved minerals or chemical additives, including hardness-related salts. For modern reporting, values are usually converted to milligrams per litre: 1 grain/UK gallon is approximately 14.25 mg/L in modern SI notation.
