Formula calculator

Three steps: the formula, the bottle, the Recipe.

Formula

Kcal per scoop Energy in one level Scoop

Displacement (mL per Scoop) Volume one Scoop adds

Don't know these? Work them out from the label

Energy per 100 mL (kcal) Only kJ on the label? Divide by 4.184.

The label gives powder as:

Scoops grams

Scoops

Water (mL)

Prepared volume (mL)

Fill in the label values to work these out.

Bottle

Target volume (mL) How much to make

Target concentration (kcal/30 mL) As prescribed

Recipe

Fill in all four values to see a Recipe.

How this works

The calculator rounds the Scoops up so there's enough energy, then rounds the water up to the nearest 5 mL. So the Actual concentration lands at or just below the Target concentration, and it warns you when that gap reaches 0.5 kcal/30 mL.
