* Milligrams (mg) measure mass or weight.
* Milliliters (ml) measure volume.
To convert between mass and volume, you need to know the density of the substance you're working with.
Here's why:
Think about a teaspoon of sugar versus a teaspoon of water. Both take up the same volume (1 teaspoon), but they have different weights (masses).
To make a conversion, you'd need to know:
* What substance you're dealing with: Is it water, oil, sugar, etc.?
* The density of that substance: Density is the mass per unit volume (often expressed as grams per milliliter).
Example:
* Water's density is approximately 1 gram per milliliter. So, 20 milligrams of water would equal 0.02 milliliters (20 mg / 1000 mg/g / 1 g/ml = 0.02 ml).
If you can tell me what substance you're working with, I can help you make the conversion.
