About the feet to inches converter
A distance stated in feet may describe ceiling height, lumber or a route segment. Combine separate feet and inches into the correct total before using a single-value conversion. The unit here is the international foot; historical survey documents may use a different definition.
One foot is exactly 12 inches, so 6 ft is 72 in. To convert feet to inches, multiply by 12; to convert back, multiply by 0.0833333333.
The international foot is defined as exactly 0.3048 m, which is 12 inches. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.
