Teaspoons are used as a measure of volume, whereas mg (milligram) is a unit of weight. There is, therefore, no direct conversion between them. It is possible to convert for a given substance, for which the density is known.
In the US, a regulation teaspoon is exactly 5ml in volume, but actual teaspoons can range anywhere from 2.5 to 6ml.
If we assume you are talking about water (for example) and standard teaspoons, then we can calculate the weight of one teaspoon of water to be 5g (since 1ml of water weighs 1g). There are 1000mg in one gram, so there are 0.0025 teaspoons of water in 12.5mg.
As you can see, this is somewhat confusing and so volumetric measurements should be avoided for solid substances and weight measurements should be avoided for liquids.
It is 5 teaspoons or just less than 1 ounce.
The conversion of milligrams to teaspoons varies depending on the density of the substance. However, as a rough estimate, 25 mg is approximately equal to 0.005 teaspoons.
Milligrams can't be converted to teaspoons. Milligrams measure mass, while teaspoons measure volume.
1010 mg of sodium is 0.2 teaspoons. It is 1/5 of a teaspoon.
15 mg is approximately three teaspoons or one tablespoon.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
That is 4 teaspoons
About 8,000 mg.
The amount of teaspoons that roughly equal 600 mg are 1.25 teaspoons. Teaspoons should not be used as accurate measurements since their amounts depend on density and approximation.
Are you guys serious? 1 ML(milli litre) is 1000 mg, 10 mg is like 3% of a teaspoons surface
I think it is about 1-1/4 teaspoons
That is 5 teaspoons.
