 1. Look up the density of a material in a table of densities (see References) if you want to determine how many milligrams are in 1 ml of the material. Density is usually expressed http://www.ehow.com/how_6954378_calculate-mg-per-m...
 If the substance in question has a density of d grams per litre (or equivalently, d mg per ml) then the conversion is. mass = volume*density. so. mg = ml*d. It should be obvious from http://wiki.answers.com/Q/What_is_the_formula_for_...
 I would be very surprised if an eyedropper had units in milligrams. Milligrams are a unit of weight, not volume - and two objects of the same weight can have vastly different volumes http://answers.yahoo.com/question/index?qid=200812...
 ml is a unit of volume while mg is a unit of weight. So they are not convertible. If it is water, 1 liter of pure water equals 1 kg (kilogram). http://www.kgbanswers.com/whats-the-conversion-for...
