A gallon of whole milk weighs 8.6 pounds, and a quart of milk weighs 2.15 pounds. To calculate the weight of milk, start by finding its volume in milliliters which is usually printed on the milk container.

Milk volume is usually written in liters, so convert it to milliliters by multiplying the volume in liters by 1,000. Then multiply the volume in milliliters by the density of milk (a known number that has been established by scientists).
