Rules
| 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 m3 |
| 1 litre |
10 000 000 mm cubed = 10 000 cm3 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 cm3 = 1000 kg per m3 = 0.0361 pounds per inch3 |
| 1 kg per m3 = 0.001 grams per m3 = 0.0624 pounds per foot3 |
| Specific Volume |
1 cm3 per gram = 0.001 m3 per kg = 27.68 inch3 per pound |
| 1 m3 per kg = 1000 cm3 per gram = 16.0185 foot3 per pound. |
| International standard atmosphere |
(1atm) = 101 325 pascals or 1.013 25 bar. This equals 1.033 23 kilogam force per cm2 or 14.6959 pound force per inch3 |
| In meteorology 1 millibar = 100 pascal |
