Surveying tenths can be converted to inches by multiplying them by a factor of 1 3/16. A tenth is equal to 1 3/16 inch, which permits a relatively simple conversion under field conditions.
Another convenient rule to remember is that 1 inch is equal to 0.0833 tenths of a foot. This allows an equally swift conversion from imperial measurements to decimal feet when needed. If working with hundredths of a foot is cumbersome, a shortcut involves converting 10 inches to 0.833 tenths, and then dividing the result by 10. Finally, many rulers and tape measures are hatched with tenths, which adds an element of precision to the measurement.
