How many milliliters are in a miligram?

Answer 1

milliliters is a measure of volume (how big?) and milligrams is a measure of mass (weight . . . sort of). You cannot convert from ml to mg or from mg to ml unless you know the density of the material being measured.

Answer 2

A milligram is a measure of WEIGHT

A milliliter is a measure of VOLUME

You can not equate WEIGHT and VOLUME directly you have to know the density of the stuff being measured to enable a conversion.

Answer 3

For a liquid with the density of 1 g/cm3, as water: 1 mL = 1 000 mg

But the mass is: m = V.d, consequently for other liquids we need the density.

Answer 4

That depend on how heavy the material in the milliliter is For example a mil of Mercury weighs a lot more then a mill of metholated spirits.

Answer 5

'milligram' is a unit of mass (or weight) 'milliliter' is a unit of volume (or space) One cannot be converted into the other.

Answer 6

Milligrams measure weight and milliliters measure volume, so it depends on the density of the measured thing.
