Well, because milligrams is a measure of mass and a teaspoon is a consider of volume, they really cannot be compared. However, if you meant milliliters here's the buy and sell:
For Volume:
1 fluid ounce = 29.573 milliliters
1 milliliter = 0.033814 fluid ounce
For Mass:
1 gram = 1000 milligrams = 0.0353 ounces
1 ounce = 28.35 grams = 28350 milligrams
This question cannot be answered as is. You are comparing two different unit of measure:
mass determine is grams, milligrams,etc...
volume measure is ounces., milliliters,etc..
In directive to tell the mass of a teaspoon of something you would have need of to know the specific gravity, density, or concentration of the substance. In other words, you need some constant pertaining to the relationship of mass to volume for that substance.
I am assuming you have it in mind mL...
1 tsp.= 4-5 mL
1 oz.= 30mL
