## Unit Conversion Tables

```Length
SI unit: Meter (m)

1 kilometer      = 1000. meters
= 0.62137 mile
1 meter		 = 100. centimeters
1 centimeter     = 10. millimeters
1 nanometer	 = 1.00 x 10-9 meters
1 picometer      = 1.00 x 10-12 meters
1 inch           = 2.54 centimeters (exact)
1 Ångstrom       = 1.00 x 10-10 meters

Volume
SI unit: Cubic meter (m3)

1 liter (L) = 1.00 x 10-3m3
= 1000. cm3
= 1.056710 quarts
1 gallon    = 4.00 quarts

Pressure
Si unit: Pascal (Pa)

1 pascal     = 1 N/m2
= 1 kg/m * s2
1 atmosphere = 101.325 kilopascals
= 760. mmHg
= 760 torr
= 14.70 lb/in2
= 1.01325 bar
1 bar        = 105 Pa (exact)

Energy
SI unit: Joule (J)

1 joule    = 1 kg * m2/s2
= 0.23901 calorie
= 1C x 1V
1 calorie  = 4.184 joules

Mass
SI unit: Kilogram (kg)

1 kilogram = 1000. grams
1 gram     = 1000. milligrams
1 pound    = 453.59237 grams
= 16 ounces
1 ton      = 2000. pounds

Temperature
Si unit: Kelvin (K)

K = 273.15 °C
K = °C + 273.15 °C
? °C = (5 °C/9 °F)(°F - 32 °F)
? °F = (9 °F/5 °C)°C + 32 °F
