How many liquid ounces in 4 liquid pounds of gravy?

Answer 1

4 lbs of water is approx 61.3 fluid ounces, adding flour would increase density, thereby decreasing the volume from 61.3 fluid ounces. Oil in the gravy would decrease the density, thereby increasing the volume from 61.3 fluid ounces. The answer would depend on the percentage of flour and oil in the gravy, ballpark figure 4 lbs of gravy would be approx 60 fluid ounces

Answer 2

16 ounces equals a pound. 4 pounds would be 64 ounces.
