Changing Units in the Customary System
Strategy When converting from a large unit to a small unit, multiply by the conversion factor.
When converting from a small unit to a larger unit, divide by the conversion factor.
Small - - - - - - - - LargeInch (in) ---------- Foot (ft)-------- Yard (yd) ------- Mile (mi)
Ounce (oz) -------------- Pound (lb) -------------Ton (t)
Fluid Ounce (fl. oz.) -- Cup (c) -- Pint (pt) -- Quart (qt) -- Gallon (gal)
Changing Units Determine the direction of the change (LS or SL)
Multiply or Divide by the appropriate conversion unit.
Example12 gal = ______ qt
L S
x12 4 (1 gal = 4 qt)
48
Example 240 in = ______ ft
S L÷40 12
3 13
Example 3 12 q = ______ c = ______ fl oz
12 x 4 = 48
48 x 8 = 384
Example 4 Comparing Convert to the same units then compare.
18 ft ______ 220 in
Convert: 18 x 12 = 216 in
Or Convert 220 ÷ 12 = 18.3 ft
18 ft ___<___ 220 in
