TABLE 7 Conversion Table Length 1 yd = 0.9144 m 12 in. = 1 ft 5280 ft = 1 mile 1 m = 3.281 ft 1 in. = 0.0254 m Time 60 sec = 1 min 3600 sec = 1 hr Mass 1 lbm = 0.4535 kg 2.205 lbm = 1 kg 1 kg = 1000 g Area 1 ft = 144 in. 2 2 10.764 ft = 1 m 2 2 1 yd = 9 ft 2 2 1 mile  = 3.098 X 10  yd 2 6 2 Volume 7.48 gal = 1 ft³ 1 gal = 3.785 l (liter) 1 l = 1000 cm³ Unit Conversion To convert from one measurement unit to another measurement unit (for example, to convert 5 feet to  inches),  first  select  the  appropriate  equivalent  relationship  from  the  conversion  table (for  this example, 1 foot = 12 inches).  Conversion is basically a multiplication by 1.  We can divide both sides of the equation 1 ft = 12 inches by 1 foot to obtain the following. Then The relationship is a conversion factor which we can use in our example to convert 5 feet to inches.
