Principle
The principle involved in measuring the specific gravity by a lactometer is that a floating object sinks until it has displaced a weight of fluid equal to its own weight. The greater is the volume of the displaced fluid, the smaller is the specific gravity of the fluid, and the lower is the lactometer reading.

Procedure
Calculation
Specific gravity = 1+ CLR\1000
SNF %( Solids Not Fat) = CLR\4 + 0.2xF + 0.36
Where F = Fat % in the milk sample.
Result and Interpretation
The lactometer reading taken at 84˚F (29˚C) is the corrected lactometer reading.
