Q&A for How to Convert Milligrams to Teaspoons

As indicated above, you have to know the density of the material before you can answer that question.

There are roughly 2,267 mg of turmeric in a teaspoon, so 400 mg would be about 0.176 tsp (one-sixth of a teaspoon). (A teaspoon is slightly different in Australia.)

Milligrams measure mass, and meters measure length, so one does not convert to the other.

First you would need a scale that measures in milligrams. Second, you need a one-gallon container. Fill the container with water. Use the scale to measure ten milligrams of the material. Pour the material into the water. If the container holds two gallons, you could fill it with water and measure out 20 milligrams of material.

It depends on the density (weight) of the liquid. For example, one teaspoon of water weighs 5 grams, but a teaspoon of vegetable oil weighs about 4½ grams. (Yes, vegetable oil and motor oil typically weigh less than water. That's why oil floats on water.)

As the above article explains, you have to specify what material you're dealing with (sugar, water, baking powder, vegetable oil, etc.) before you can convert milligrams to teaspoons.

One teaspoon of ground flaxseed weighs about 2500 milligrams. Therefore, 40 mg consists of roughly 1/60 of a teaspoon.

Since a "spoonful" has no specific volume, that question can't be answered. However, one milliliter is defined as roughly 0.2 US teaspoon, so 15 ml would be approximately 3 teaspoons.

5 milliliters are approximately equivalent to one teaspoon. 10 ml would be 2 teaspoons.

One milliliter equals approximately 0.2 teaspoon. So 48 ml equals roughly 9.6 teaspoons.

1 ml equals 0.2 tsp, so 15 ml equals (15 ml)(0.2 tsp/1 ml) = 3 tsp.
