A gallon of milk weigh 8.601 lb and half of milk weigh 4.3 lb
The density of milk = The density of cow’s milk depends on the temperature; for homogenized and pasteurized fresh milk containing 3.5% fat at a temperature of 20 ° C.
How do we calculate a gallon of milk weigh?
Gallon= 3.785 litre
Now, we got its weighs, 3.785kg (Simple)
Specific Gravity of raw milk =1.033
Gravity X Weigh= Actual Weigh
1.033 X3.785 =3.909 kg
3.909 kg X2.2 =8.6 lb
½ (half) gallon= 8.6/2 =4.3 lb
