It depends The answer is "it depends."
If we don't know what the teaspoon is holding, then we can't answer the question. That's because a milligram is a unit of WEIGHT, whereas a teaspoon is a unit of volume.
So what? you ask. Well, a teaspoon of black pepper will not weigh the same as a teaspoon of iron filings, which will have a different weight than a teaspoon of sugar, which will have a different weight than a teaspoon of tungsten filings or liquid Mercury.
Do not confuse WEIGHT with VOLUME.
For example, a level teaspoon of table salt has (weighs) about 2300 milligrams. FYI, the recommended daily allowance (RDA) is 2400 milligrams. And average consumption in the USA is 3500 milligrams. Drop the dill pickle and back away!
There are 10 milligrams in one teaspoon.

The teaspoon as a volume unit has 5 mL.
Mass = volume x density; density is a specific characteristic of any material. So the mass contained in a teaspoon depends on the density.
A.
A milligram (and gram) is a measure of weight (or masss) and a teaspoon is measure of volume. To convert between mass and volume, you need to know the density of the material. A teaspoon of lead weighs many more milligrams than a teaspoon of feathers! ONLY knowing the density of the material can you convert from teaspoons to milligrams or vice versa. B. To answer how many ounces are in a milligram, the conversion would be: 1 ounce/28 grams X 1 gram/1000 milligrams = 1/28,000 of an ounce in 1mg or 0.0000357th of an ounce in one milligram
1 mL = about 0.2 teaspoons.
1 milliliter = 0.202884136 US teaspoons
HOW MANY TEASPOONS ARE IN A MILLIGRAM
0.2 metric teaspoons
1ml is 0.2 metric teaspoons
167.58 ml 1 milliliter equals 0.202 US teaspoons. 1 teaspoon is 4.92 milliliters
2.33 tsp 1 milliliter equals 0.202 US teaspoons. 1 teaspoon is 4.928 milliliters
152.16 tsp 1 milliliter equals 0.202 US teaspoons. 1 teaspoon is 4.928 milliliters
9 metric teaspoons
That is approximately 5.9 teaspoons
0.2 metric teaspoons
32 US teaspoons = about 157.725 mL
375 mL = about 76.08 US teaspoons.
100 mL = about 20.3 US teaspoons.
0.9 mL = about 0.18 US teaspoons.
That is approximately 100 teaspoons
10.14 tsp
a teaspoon is approximately 5 ml, and tablespoon 25
There are 15 ml in 3 teaspoons, therefore there would be 10 mL's in 2 teaspoons.
0.32 tsp 1 milliliter equals 0.202 US teaspoons. 1 teaspoon is 4.928 milliliters
