How many teaspoons equal 30mg?

You can't directly convert milligrams (mg) to teaspoons. Here's why:

* Milligrams measure weight or mass. They are used to describe the amount of a substance.

* Teaspoons measure volume. They are used to measure the space a substance occupies.

To make a conversion, you need to know what substance you're working with. Different substances have different densities (mass per unit volume).

For example:

* 30mg of sugar would take up a different volume than 30mg of salt.

To make a conversion, you'd need:

1. The density of the substance: This tells you how much mass is contained in a certain volume.

2. A conversion factor: This helps you relate teaspoons to a specific volume unit (like milliliters).

Let me know if you have a specific substance in mind, and I can help you calculate the equivalent teaspoon measurement.
