Q: Why are the serving sizes for AFA and Blue Majik both 1 gram, but AFA is 1/2 teaspoon, whereas BM is 1 teaspoon?
A: The serving size is by weight, not volume. This is due to different mesh size of each product.
example: the weight of 1 teaspoon of granulated sugar vs 1 teaspoon of powdered sugar. Same volume (1 teaspoon) but different weights.
volume = the amount of space something takes up
weight = a measure of the heaviness (or lightness)
