10 ml equals how many mg?

Answer 1

It depends on the density of the material you are measuring. Once you know the density, multiply it by the number of milliliters and you have milligrams.

For water, the answer is 1000 mg (Since the density of water is 1).

Answer 2

This question cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A milligram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

As a simple mental exercise consider a millilitre of air and a millilitre of water. They will have very different masses.

Answer 3

This is impossible without knowing the substance... density plays a key role in converting mass to volume.

Answer 4

Does not convert; milligrams (mg) and grams are measures of weight or mass and mL (milliliters) is a measure of volume.

Answer 5

10mg
