0.5 gallons of milk equals 4.30 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, 0.5 gallons of all-purpose flour would be 2.21 lb.
Formula and Step-by-Step
- Start with 0.5 gallons of milk
- 1 gallon of milk = 3,904g
- 0.5 × 3,904 = 1,952g
- Convert grams to pounds: 1,952 ÷ 453.592 = 4.30 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.
