How the formula works
Both gram per milliliter and milligram per liter 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 1e6 to get milligram per liter. To reverse the conversion, multiply a milligram per liter value by 1e-6 to get back to gram per milliliter.
