There is no way to add a unit of measure to an entry. You could create your own entry and choose whatever unit of measure you want that way, but that would take more work than converting it to grams.
But, how is using grams silly? Most of the world uses grams. It's the same as measuring by pounds/ounces, just a different number. They even provide a conversion calculator so you can put in the number of ounces (so in this case, 24) and it will spit out how many grams it is (approx 680 in this case). Even if you google "grams to ounces calculator", a calculator will come up.
