1.5 gallons of milk equals 12.91 lb. Milk has a density of 244g per cup (3,904g per gallon), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 1.5 gallons of all-purpose flour would be 6.62 lb.
Formula and Step-by-Step
- Start with 1.5 gallons of milk
- 1 gallon of milk = 3,904g
- 1.5 × 3,904 = 5,856g
- Convert grams to pounds: 5,856 ÷ 453.592 = 12.91 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
