🥄 mg → tbsp Converter
Estimate tablespoon volumes from milligram masses.
Useful for supplement dosing, DIY recipes, and cosmetics when masses are listed in mg but measuring spoons dispense by volume.
Pure water at ~4°C.
Tablespoons: 0.33814 tbsp
Teaspoons: 1.014421 tsp
Milliliters: 5
How to Use This Calculator
Enter milligrams
Type the measured mass in mg.
Select density
Choose a preset liquid or provide custom density in g/cc.
Review tablespoons
Use the tablespoon, teaspoon, and milliliter outputs for dispensing.
Formula
Mass (g) = mg ÷ 1,000
Volume (cc) = Mass (g) ÷ Density (g/cc)
Tablespoons = cc ÷ 14.7867647813
Teaspoons = cc ÷ 4.92892159375
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Spoon measurements are convenient but depend on the substance density. This converter translates milligram masses into familiar kitchen volumes so you can portion liquids even when instructions list weight.
Preset densities cover common fluids; customize the value when dealing with syrups, creams, or powdered slurries.
Frequently Asked Questions
Can I convert tablespoons back to mg?
Multiply tablespoons by 14.7867647813 to get cc, then multiply by density (g/cc) and by 1,000 for mg.
Does it work for powders?
Yes, provided you know the bulk density in g/cc.
What about dry vs liquid tablespoons?
The converter assumes U.S. liquid tablespoons. Adjust the factor if you use a different definition.
Does temperature matter?
Density varies with temperature. Enter the density measured at your operating point for best accuracy.
