Pounds and gallons are both commonly used to measure cooking ingredients.įor cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements. Gallons = 5 lb / 8.3454 × 0.7 g/mL = 0.8559 gal When to Convert Pounds to Gallons If the density is given in grams per milliliter (g/mL), then first multiply the density by 8.3454 to convert to lb/gal.įor a density given in g/mL, you can use this simple formula to convert:

Note that in order for this to work, the density must be in pounds per gallon (lb/gal). To convert a measurement in pounds to gallons, divide the weight by the density of the ingredient or material.

Therefore, to convert between pounds and gallons of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion. In this case, we need to account for the density of the substance whenever we do a conversion. Since pounds are a unit of mass and gallons are a unit of volume, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them.
