There are two different weight classes for grains the one involved here is 7000 per pound. So if you (7000/453.8)xthe weight called for you would know how many grains to substitute.
I handload. My scale is an Ohaus 0 -500? With a capacity of 500 grains, and 0.1 grain resolution. Next on my list will be a RCBS "digital" - greater capacity, same resolution, with the capability to shift to metric units.

Lest anyone working with gunpowder get confused and start throwing pieces of rifle/ pistol action metal around ... There are 7000 grains to one pound. That works out to 437.5 grains per ounce, and 28.35 grams per ounce; 15.43 grains per gram.
