How many milligrams would be equal to a mililiter?

Answer 1

milligrams is a measure of mass and milliliters is a measure of volume for fluids. To convert milligrams to milliliters you need to know the density of the fluid.

The Greek letter ρ is often used to denote density.

ρ m/V where m mass and V volume. The mass of a fluid in milligrams is then

m ρV where the density needs to be expressed in milligrams/millilter. Common units for density are grams/cubic centimeter which is the same as grams/milliliter and kilograms /cubic meter. You will need to make the appropriate conversion.
