Calculate milk solids from milk weight or litres using typical whole or skim milk values or your own solids %, or find the powder needed for a target.

Find the non-water (fat, protein, lactose and minerals) mass of a milk batch.

Typical values; pick Custom to enter a measured total-solids percentage.

Optional settings
Blank omits fat and solids-not-fat estimates. This describes the original batch.

Milk Solids Formula

The following two example problems outline the steps and information needed to calculate the Milk Solids.

MS = WM × S / 100

Variables:

  • MS is the Milk Solids (g)
  • WM is the total weight of milk (g) 
  • S is the total percentage solids (%) 

To calculate milk solids, multiply the mass of the milk by the total-solids percentage divided by 100. Reverse mode uses S = 100 × MS / WM. For powder addition, x = M(T − C)/(P − T), where C, T and P are current, target and powder total-solids percentages on the same mass basis; for an increase, P must exceed T. The added powder changes the final batch mass.

How to Calculate Milk Solids?

The following steps outline how to calculate the Milk Solids.

  1. First, determine the total weight of milk (g). 
  2. Next, determine the total percentage solids (%). 
  3. Next, gather the formula from above = MS = WM * S/100.
  4. Finally, calculate the Milk Solids.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total weight of milk (g) = 50

total percentage solids (%) = 12.5

MS = WM * S/100 = 50 × 12.5/100 = 6.25 g
