GENERAL EQUIVALENTS
1 kilometer	1000 meters = 0.62137 miles
1 mile	1609.34 meters = 1.60934 kilometers
1 acre	4046.86 m squared = 0.404686 hectare
1 hectare	1.000 *10 000 m squared = 2.471 acre
1 U.S. Barrel	42 U.S. gallons (petroleum measure) = 34.97 Imp. Gallons = 0.159 m 3
1 litre	10 000 000 mm cubed = 10 000 cm 3 or 1 cubic decimeter
	1.76 U.K pints = 2.133 U.S. pints.
1 Pascal	1 newton per square meter
1 millimeter	Hg is also called "torr"
1 joule	1 newton meter
1 watt	1 joule per sec = 1 newton meter per sec
Density	1 gram per cm 3 = 1000 kg per m 3 = 0.0361 pounds per inch 3
	1 kg per m 3 = 0.001 grams per m 3 = 0.0624 pounds per foot 3
Specific Volume	1 cm 3 per gram = 0.001 m 3 per kg = 27.68 inch 3 per pound
	1 m 3 per kg = 1000 cm 3 per gram = 16.0185 foot 3 per pound.
International standard atmosphere
	(1atm) = 101 325 pascals or 1.013 25 bar. This equals 1.033 23 kilogam force per cm 2 or 14.6959 pound force per inch 3
In meteorology 1 millibar = 100 pascal
