CONVERSION OP WEIGHTS INTO PERCENTAGES. 3 



DIRECTIONS FOR USING THE TABLES. 



Table I shows the percentage equivalents for separations weighing 

 from 0.1 to 20 grams taken from samples weighing from 25 to 65 

 grams, inclusive, which covers the entire range of maximum and 

 minimum limits of color, wheat of other classes, damaged kernels, 

 and inseparable impurities specified in the numerical grades of the 

 United States standards for wheat.

Table II shows percentage equivalents for separations weighing 

 from 0.1 to 40 grams taken from samples weighing from 240 to 260 

 grams, inclusive, which covers the entire range of maximum limits 

 of corn of other colors, damage, heat damage, and foreign material 

 and cracked corn specified in the numerical grades of the United 

 States standards for shelled corn. 



The solution of the following problem will illustrate the use of the 



table : 



Problem. — A sample weighing 240 grams contains 8 grams of damaged corn. What 

 is the percentage of damaged corn contained in the sample?
