TABLE OF AMERICAN, ENGLISH AND FRENCH
PROOF OF SPIRITS.
By United States Custom-House hydrometer (Tralle scale), at a temper-
a t ure of sixty degrees Fahrenheit:
100 degrees absolute alcohol equals 200
100 degrees absolute alcohol equals 175.25
100 degrees absolute alcohol equals 100
degrees America n proof.
degrees Sykes proof .
degrees Gay Lussac proof.
TO CH ANGE SYKES PROOF INTO AMERICAN PROOF.
Multiply Sykes degrees expressed in hundreds by 114.1, and the result
will
correspond with American proof.
Example.-12.2
above proof Sykes, say 112.2 proof. 112.2 X 114.1 =
128.0202, practically 28 above proof American.
Ex ample.-24.6
below proof Sykes, say 75.4 proof. 75.4 X
1J
4.1 = 86.0314,
practically 14 below proof American.
TO CHANGE AMERICAN PROOF I NTO S YKES PROOF.
Multiply half the American proof (its equivalent in absolute alcohol) by
1 . 7525, and the difference between the product a nd 100
will
gi ve the degrees
of Sykes, either above or below proof.
Example.-28
above proof America n, say 128 proof= 64 alcohol. 1.7525
X 64 = 112.1600, practically 12.2 above proof Sykes.
Example.-6
below proof American, say 94 proof= 47 alcohol. 1.7525 X
47 = 82.3675, practically 17.6 below proof Sykes.
