Linear Measure
2.54 cm = 1 in
12 in = 1 ft
5280 ft = 1 mi
1 m = 3.28 ft
1 km = 0.621 mi
1 furlong = 660 ft
Weight/Mass
1 stone = 14 lbs
1 lb = 0.454 kg
1 oz = 28.3 g
16 oz = 1 lb
1 metric ton = 1.10 ton
1 metric ton = 103 kg
Volumetric Measure
1 cm3 = 1 mL
1 gal = 3.78 L
14.79 mL = 1 tbsp.
1 m3 = 103 L
1 cup = 237 mL
1 gal = 4 quarts
Time
60 s = 1 min
60 min = 1 hr
24 hr = 1 day
365 day = 1 yr
10 yr = 1 decade
100 yr = 1 century


  1. 1.2 × 10-3 m3 to cm3
  2. 11 m3 to ft3
  3. 9.40 × 10-2 ft2 to in2
  1. 6.44 × 109 m3 to mi3
  2. 5.70 × 105 km2 to mi2
  3. 1.5 × 103 ft2 to m2






  1. The Greenland ice sheet has a volume of 6.3 × 105 cubic miles. What is the volume of ice in cubic kilometers?
  2. “In 2006, estimated monthly changes in the mass of Greenland’s ice sheet suggest that it is melting at a rate of about 239 cubic kilometers per year. These measurements came from the US space agency's Grace (Gravity Recovery and Climate Experiment) satellite, launched in 2002, as reported by BBC.” What is this rate in cubic miles per year? (From the Wikipedia page about the Greenland ice sheet.)
  3. At the rate given in the previous problem how many years will it take for the whole Greenland ice sheet to melt? (This rate is likely to be variable and will depend on changes in human activity with regard to greenhouse gas emissions.)
