Convert from township to caliber

Unit Definition (township)
A Township in the United States refers to a small geographic area, ranging in size from 6 to 54 square miles (15.6 km² to 140.4 km²), with 36 square miles (93 km²) being the norm.

Unit Definition (caliber)
The caliber is a unit used to express the bore diameter of a gun. Traditionally, the diameter is stated in inches, so that ".22 caliber" refers to a pistol having a bore of 0.22 inches (5.588 mm). So the caliber is actually equivalent to the inch. The usage of the term "caliber" is actually now in decline, because bore diameters of many guns are now stated in millimeters. "Caliber" is the American spelling; elsewhere the unit is often spelled "calibre."
