Enter a volume in CC and a powder density to calculate mass in grams, or enter mass to find volume. Density defaults to 0.4 g/cc (loose whey protein).

Grams of Powder Formula
GP = CC * D
Variables:
- GP = Grams of Powder (mass in grams)
- CC = volume in cubic centimeters (1 cc = 1 mL exactly)
- D = bulk density of the powder (g/cc)
The relationship is linear: doubling the volume doubles the mass, and the only variable that changes between different powders is density. The default value of 0.4 g/cc represents loose whey protein powder. Using the wrong density value introduces proportional error, so selecting the correct density is the critical step.

Loose vs. Tapped Density
Every powder has two relevant density states. Loose (or bulk) density is measured when powder is freshly poured with no compression. Tapped density is measured after the container has been tapped or vibrated, allowing particles to settle into a tighter arrangement. For most powders, tapped density runs 15 to 40 percent higher than loose density.
This gap matters practically: a supplement scoop that delivers 5 grams when heaping-full delivers significantly less when the container has been sitting and the powder has settled at tapped density. For creatine monohydrate, the loose-to-tapped ratio of 0.90 to 1.10 g/cc means a 5 cc volume swing between a freshly opened jar and a half-empty one that has been shaken. When precision matters, always weigh rather than scoop.
FAQs
Is 1 cc the same as 1 mL?
Yes. One cubic centimeter and one milliliter are identical units of volume, both equal to 1/1000 of a liter. The terms are used interchangeably in measurement and medicine.
Why does my supplement scoop give inconsistent gram readings?
Volume scoops measure a fixed number of cc, but mass per scoop depends on whether the powder is loose, packed, or settled. Tapped density can be 15 to 40 percent higher than loose density for the same material, so scooping from a just-opened versus half-empty settled container produces different masses. For consistent dosing, weigh on a scale.
What is the density of protein powder?
Whey protein powder has a typical loose bulk density of 0.36 to 0.45 g/cc, with 0.40 g/cc being a common manufacturer target. A standard 25 cc scoop at 0.40 g/cc yields approximately 10 grams. Plant-based protein powders tend to be slightly denser (0.45 to 0.55 g/cc) due to finer particle size.
What is the density of creatine monohydrate?
Creatine monohydrate has a loose bulk density of approximately 0.90 g/cc, meaning 5 cc of creatine powder weighs about 4.5 grams. A typical 5 gram serving occupies roughly 5.5 cc loose. Because creatine is denser than protein powder, many users underestimate its volume when scooping.
Can this calculator be used for medications?
This calculator estimates mass from volume using bulk density. Pharmaceutical powders vary widely from 0.14 g/cc (excipients and fillers) to over 1.0 g/cc depending on formulation. For any medication, always use the labeled weight dose rather than a volume estimate, since even small density variations affect concentration.
Why does flour density vary between brands?
Flour density depends on protein content, grind fineness, and moisture. All-purpose flour typically runs 0.55 to 0.63 g/cc loose; bread flour with higher protein content is slightly denser. Sifted flour can drop to 0.45 g/cc because aeration increases volume without changing mass. This is why baking recipes measured by cup volume benefit from weight-based measurements instead.
