How the formula works
Both gram per milliliter and milligram per milliliter measure the same physical quantity (mass per unit volume), so converting between them is a single multiplication. Multiply a value in gram per milliliter by 1000 to get milligram per milliliter. To reverse the conversion, multiply a milligram per milliliter value by 0.001 to get back to gram per milliliter.
