1 tsp is equals to 4200 mg, use this teaspoon to milligram converter is used for conversion from tsp to mg using mg = tsp × density × 4928.92 formula.
Converting between these units can be challenging because teaspoons measure volume, while milligrams measure weight. The conversion depends on the density of the substance being measured, as different materials have different weights for the same volume.
This conversion is particularly useful in cooking, baking, and pharmaceutical applications where precise measurements are crucial.
The tsp to milligram calculator helps bridge the gap between volume-based measurements (teaspoons) and weight-based measurements (milligrams).

tsp to mg Conversion Formula
The conversion formula from teaspoons to milligrams is:
$$ \text{mass (mg)} = \text{volume (tsp)} \times \text{density (mg/tsp)} $$
Where:
- mg is the weight in milligrams
- tsp is the volume in teaspoons
- density is the substance’s density in grams per milliliter (g/mL)
- 4928.92 is a conversion factor (1 tsp = 4.92892 mL)
Some common substances and their conversion factors from teaspoons (tsp) to milligrams (mg):
- Water: 1 tsp ≈ 4920 mg
- Salt: 1 tsp ≈ 6000 mg
- Sugar (granulated): 1 tsp ≈ 4000 mg
- Baking Soda: 1 tsp ≈ 4800 mg
- Flour (all-purpose): 1 tsp ≈ 2500 mg
- Butter: 1 tsp ≈ 4540 mg
How many milligrams is a teaspoon?
Let’s consider a few common examples:
- Water: 1 tsp ≈ 4928.92 mg (density: 1 g/mL)
- Table Salt: 1 tsp ≈ 5687.5 mg (density: 2.16 g/mL)
- Granulated Sugar: 1 tsp ≈ 4200 mg (density: 0.85 g/mL)
- All-Purpose Flour: 1 tsp ≈ 2957.35 mg (density: 0.6 g/mL)
As you can see, the milligram equivalent of a teaspoon can vary significantly based on the substance’s density.
What Is a Milligram?
A milligram (mg) is a unit of mass in the metric system. It is equal to one-thousandth (1/1000) of a gram or 0.001 grams. Milligrams are commonly used to measure very small amounts of substances, particularly in:
- Pharmaceuticals: Drug dosages are often specified in milligrams.
- Nutrition: Vitamin and mineral content in foods are typically listed in milligrams.
- Scientific research: Many experiments involve measuring small quantities of chemicals or compounds.
The milligram provides a precise way to measure tiny amounts that would be difficult to quantify using larger units like grams or ounces.
