How much does a US gallon of milk (full jug) weigh?
US gallon of milk (full jug) weighs about 4 kg (8.7 lb).
💧 That's about the weight of 4 liters of water — or 3 laptops 💻, or 10 cans of soda 🥤.
At 4 kg, it ranks #20 of 24 in Food & Drink (lightest to heaviest) — heavier than Full wine bottle (1.3 kg) and lighter than Carving pumpkin (6.5 kg).
This is a specific, standardized product, so the weight above is an exact figure — not an average across variants.
Milk is slightly denser than water, so a gallon of milk outweighs a gallon of water.
