Rules for Figuring Tapers
| GIVEN
| TO FIND
| RULE
| | The taper per foot
| The taper per inch
| Divide the taper per foot by 12
| | The taper per inch
| The taper per foot
| Multiply the taper per inch by 12
| | End diameters and lenght of taper in inches
| The taper per foot
| Subtract small diameter from large;divide by length of taper, and multiply quotient by 12
| | Large diameter and lenght of taper in inches, and taper per foot
| Diameter at small end in inches
| Divide taper per foot by 12; multply by length of taper, and subtract result from large diameter
| | Small diameter and length of taper in inches, and taper per foot
| Diameter at large end in inches
| Divide taper per foot by 12; multiply by length of taper, and add result to small diameter
| | The taper per foot and two diameters in inches
| Distance between two given diameters in inches
| Subtract small diameter from large; divide remainder by taper per foot, and multily quotient by 12
