I would like to know the difference in feet and inches of an elevation of 671.55 to 670.13

The units are decimal feet. The difference is 1.42 ft, multiply the fractional part (0.42) by 12 to get 5.04 inches, so 1 ft 5.04 inches.

As an alternative just multiply 1.42 ft x 12 in/ft to get 17.04 inches, all in inches.
