Common Unit Conversion Equivalencies

U.S. Customary System
Length     1 ft  =  12 in     1 yd  =  3 ft     1 mi  =  5280 ft   Weight (Mass)     1 lb  =  16 oz     1 tn  =  2000 lb   Temperature     32°F  =  freezing point of water     212°F  =  boiling point of water	Volume (Capacity)    1 c  =  8 oz    1 pt  =  16 oz    1 qt  =  32 oz    1 gal  =  4 qt  Time    1 min  =  60 sec    1 hr  =  60 min    1 day  =  24 hr    1 wk  =  7 days    1 yr  ~  365.25 days

Metric (SI) System
Length     1 mm  =  1/1000 m     1 cm  =  1/100 m  =  10 mm     1 km  =  1000 m   Weight (Mass)    1 mg  =  1/1000 g    1 kg  =  1000 g    1 t  =  1000 kg   Temperature     0°C  =  freezing point of water     100°C  =  boiling point of water	Volume (Capacity)     1 mL  =  1/1000 L  =  1 cc      1 kL  =  1000 L  Time    1 msec  =  1/1000 sec    1 min  =  60 sec    1 hr  =  60 min    1 day  =  24 hr    1 wk  =  7 days    1 yr  ~  365.25 days

U.S. Customary System  « — »  Metric System
Length     1 in  =  2.54 cm      1 mi  ~  1.61 km   Weight (Mass)     1 oz  ~  28.4 g     1 kg  ~  2.2 lb	Volume (Capacity)     1 oz  ~  29.6 mL     1 gal  ~  3.8 L   Temperature     #°F  =  9(#°C)/5 + 32       #°C  =  5(#°F - 32)/9
Time      n.a.  (units of time measure are basically the same in both systems)
