Customary Units

Customary Lengths

in= inch               12 in.= 1 ft

ft= foot                3 ft.= 1 yd

yd = yard              5,280 ft.= 1 mi

mi= mile               1,760 yd.= 1 mi

 You would use this information in a problem like this,

13 ft + 15 ft.

Well, 13 ft + 15 ft  = 28 ft


So, if you know 12 inches are in 1 foot you know that 24 inches is 2 feet.


Now, you have 4 inches left.


So your answer is 2 feet and 4 inches.
