Milligrams are used to measure the mass of something not the volume.
For the sake of argument, let us assume that the liquid that you are talking about has the same density as water. This would mean that the 40 milligrams that you propose would also measure out to 40 milliliters of volume.
400 mg is about 1/12 of a teaspoon. ------------------------------------------------- You can not equate a unit of volume (the teaspoon) with a unit of mass (the mg) because it depends on what you are measuring (its density).
There are 1000000 milligrams in a kilogram. Therefore 40 milligrams is 0.00004 kilograms.
40 milligrams = 0.0000882 pounds (approx).
That is 240 teaspoons
milli- means one thousandth 40 grams = 40 000 milligrams
There are about 8 teaspoons in 40 grams.
There are approximately 80 tablespoons in 40 ounces.
200 gm = 40 teaspoons
That is 8 teaspoons.
that is 8 teaspoons.
There are 3 teaspoons in a tablespoon. So 40 teaspoons is 13.333 tablespoons.
There are 40 000 000 milligrams
