I need to convert Grain/cubic foot to Grain/cubic inch.
As 12 inches equals 1 ft, the volume contained in 12 inches x 12 inches x 12 inches is equal to the volume in 1 ft x 1 ft x 1 ft. 12" cubed is 1728 in^3, so to convert the density of gr/ft^3 to gr/in3, simply divide by 1728:
(1728 gr/ft^3) / (1728 in^3/ft^3) = 1 gr/in^3
