Conversion Tables

The following tables provide the most frequent conversions for use in vacuum applications. Text books or other reference manuals offer additional conversion factors.
In all of the tables below, the original units are listed in the lefthand column. Locate the conversion factor by intersecting the row of the original units with the column of the final units.
Multiply the number of original units by the factor to obtain the number of final units.
Using the sample table at the right, gram weight is multiplied by 3.527E-02 to obtain ounce weight. For example, 281 grams would convert to ounces by: 281 x .03527 = 9.911  10 oz. 
Note that conversion factors are intended for reference use only.
