Daily sodium and sugar limits are often given in milligrams. This converter shows how many teaspoons that is for salt, sugar and other ingredients.
How to use the mg to Teaspoons Converter
- Ingredient
- Custom density
- Milligrams
- Every result field is editable: type into Teaspoons (US) or any other result and Milligrams plus every other field update to match.
Results update as you type, and every field accepts the units shown in its menu.
How it works
The calculator converts your weight to SI units, looks up the density of the selected ingredient in kg/m³ and divides. The result is then shown in teaspoons (US) and other common units. Every result field is editable, so you can work backwards too.
How to convert milligrams to teaspoons (US)
- Find the density of the ingredient (the menu fills it in for you).
- Convert the weight to SI units if needed.
- Divide mass by density to get volume.
- Convert the answer to teaspoons (US).

Good to know
Salt (sodium chloride) is about 39% sodium by mass. A limit of 2,300 mg sodium equals about 5.8 g, or roughly one level teaspoon, of table salt.
Inputs explained
| Field | What to enter |
|---|---|
| Ingredient | Choose one: Water, Milk (whole), Heavy cream, Plain yogurt … |
| Custom density | Units: g/cm³, kg/m³, kg/L, lb/ft³, lb/US gal |
| Milligrams | Units: mg, kg, g, µg, dag, t … |
What each result means
- Teaspoons (US) = [Milligrams] ÷ [Density used]
- Tablespoons (US) = [Milligrams] ÷ [Density used]
- Millilitres = [Milligrams] ÷ [Density used]
Formula
volume = mass ÷ densityWorked example
Inputs — Ingredient: Table salt; Custom density: 1 g/cm³; Milligrams: 2,300 mg.
Results — Density used = 1.217 g/cm³; Teaspoons (US) = 0.383429 tsp; Tablespoons (US) = 0.12781 tbsp; Millilitres = 1.889893 mL.
Frequently asked questions
How many teaspoons is 2,300 mg of salt?
About 0.38 tsp of salt (note: 2,300 mg of sodium is about 5.8 g of salt, roughly 1 tsp).
How many mg in a teaspoon of sugar?
About 4,200 mg.
Why does the answer change with the ingredient?
Milligrams and teaspoons (US) measure different things (weight and volume), so the conversion depends on how dense the material is.
What if my ingredient is not listed?
Choose “Custom density” and type its density; the label or a quick weigh-and-measure test will give it.
What formula does the mg to Teaspoons Converter use?
volume = mass ÷ density.
