How to Convert a Teaspoon of Whey Protein Powder to Milligrams
Teaspoons measure volume. Milligrams measure mass. To convert between them you need the substance density.
For Whey Protein Powder, the density is approximately 0.48 g/mL. Whey protein isolate bulk density averages ~0.480 g/mL. 1 US tsp = ~2,366 mg.
Formula
mg = tsp × 4.92892 mL × 0.48 g/mL × 1000Example: 1 tsp of Whey Protein Powder = 1 × 4.92892 × 0.48 × 1000 = 2,365.88 mg
