NANOGRAM/CUBIC MILLIMETER TO GRAIN/CUBIC FOOT (ng/mm³ TO gr/ft³) FORMULA
To convert between Nanogram/cubic Millimeter and Grain/cubic Foot you have to do the following:
First divide 1.0E-12/1.0E-9 / ((0.45359237/16)*(192/175)/480)/((0.0037854118/231)*1728) = 0.43699573
Then multiply the amount of Nanogram/cubic Millimeter you want to convert to Grain/cubic Foot, use the chart below to guide you.
