ALTANA Pfund Cryptometer - Manual (Page 8)

The formulas used to construct the above Table 1
may be simplified as follows
H. P. = 40.7/K x L
and
T =
K x L x 39.4
WHERE
H. P = Wet Hiding Power
(in square feet per gallon)
K = Top Plate Wedge Constant (slope)
L = Cryptometer Setting (in millimeters)
T = Wet Film Thickness (in mils or
thousandths of an inch)
