To obtain equivalent weights of heavier papers, take the column which is a multiple of the weight, and multiply, e.g., 72 lb. demy, equivalent in atlas required; 24 lb. demy: 53.88; 72=53.88 × 3 = 161.64 = 162 lb. Or take the unit column from table, multiply and add, e.g., demy 65 lb., equivalent weight required in super-royal printing; 6 lb. demy=8.59 super-royal. 60 lb.=85.9; 5 lb. =7.16=93.06=93 lb. super-royal. The table may, of course, be used to obtain all equivalents, such as imperial, 40 lb.; required weight of demy=24 lb. demy. The nearest whole number should be taken, except when ordering regular stock weights.
