🥄 mg → tsp Converter
Estimate teaspoon measures from milligram masses.
A quick reference for liquid supplements, tinctures, and recipe adjustments where dosages start in mg but spoons dispense by volume.
Pure water at ~4°C.
Teaspoons: 0.50721 tsp
Tablespoons: 0.16907 tbsp
Milliliters: 2.5
How to Use This Calculator
Enter milligrams
Type the mass you need to dispense in mg.
Select density
Choose a preset fluid or enter your own density in g/cc.
Dispense teaspoons
Use the teaspoon and tablespoon results to measure with spoons.
Formula
Mass (g) = mg ÷ 1,000
Volume (cc) = Mass (g) ÷ Density (g/cc)
Teaspoons = cc ÷ 4.92892159375
Tablespoons = cc ÷ 14.7867647813
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
When instructions list micro-dose masses but equipment measures in kitchen spoons, density-based conversion gives you an accurate target volume. This calculator ensures that conversions remain precise regardless of the liquid involved.
Adjust the density to match oils, syrups, or solutions so dosing stays consistent and repeatable.
Frequently Asked Questions
Can I convert tsp back to mg?
Yes. Multiply teaspoons by 4.92892159375 to get cc, multiply by density (g/cc), then multiply by 1,000 for mg.
Does it work for powders?
Yes, provided you use the bulk density for the powder in g/cc.
Why show tablespoons and mL?
These extra units help when scaling up recipes or using metric syringes.
Is the teaspoon U.S. standard?
Yes. Adjust the conversion factor if you use a different teaspoon definition.
