Changing Units In The Customary
System
Length
12 inches (in.) = 1 foot (ft)
3 feet = 1 yard (yd)
5,280 feet = 1 mile (mi)
Weight
16 ounces (oz) = 1 pound (lb)
2,000 pounds = 1 ton (t)
Capacity
8 fluid ounces (fl oz) = 1 cup (c)
2 cups = 1 pint (p)
2 pints = 1 quart (qt)
4 quarts = 1 gallon (gal)
10 gal = ____ c
qt = ___ p
____ ft = 2 yd 2 ft
260 oz = ____ lb
2 mi = ____ ft
