* Milliliters (ml) measure volume, which is the amount of space a substance occupies.
* Milligrams (mg) measure mass, which is the amount of matter in a substance.
To convert between ml and mg, you need to know the density of the substance. Density is the mass per unit volume.
Here's how to think about it:
Imagine you have 60 ml of water. Water has a density of approximately 1 g/ml. This means 1 ml of water weighs 1 gram (or 1000 mg).
Therefore, 60 ml of water would weigh 60 grams (or 60,000 mg).
To convert ml to mg, you need to know the density of the substance you are measuring.
