To convert milliliters (ml) to milligrams (mg), you need to know the density of the substance you're measuring, as mg is a measure of mass and ml is a measure of volume. For water, 1 ml is approximately equal to 1000 mg, so 0.25 ml would equal about 250 mg. However, for other substances, you'll need to multiply the volume by the specific density to get the mass in milligrams.
