Proper measurement is important. Some ingredients can be dangerous when mishandled. We also recommend you measure your product on receipt to confirm total weight or volume.
Powders:
Scoops measure volume and scales measure mass. We strongly recommend you do not rely on a “microscoop” as the density of powder can vary.
We recommend using a precise milligram scale. Milligram scales with a precision of ±3mg are available on Amazon.com for <$20. Please read the following article to learn more about scales and precision:

Once you have confirmed the total powder weight you can create a solution for more accurate volumetric measurement. See the question below on how to make a chemical solution.
Solutions:
Solutions are measured by volume. We recommend using a graduated beaker or pipette to measure volume.
