Length [SI unit: meter (m)] |
Mass [SI unit: kilogram (kg)] |
|---|---|
|
1 meter = 1.0936 yards |
1 kilogram = 1000 grams = 2.2046 pounds |
|
1 centimeter = 0.39370 inch |
1 pound = 453.59 grams = 16 ounces |
|
1 inch = 2.54 centimeters (exactly) |
1 ton = 2000 pounds = 907.185 kilograms |
|
1 kilometer = 0.62137 mile |
1 metric ton = 1000 kilograms = 2204.6 pounds |
|
1 mile = 5380 feet = 1.6093 kilometers (exactly) |
1 atomic mass unit = 1.66056 x 10-27 kilograms |
|
1 angstrom = 10-10 = 100 picometers |
|
|
Volume [SI unit: cubic meter (m3)] |
Temperature [SI unit: kelvin (K)] |
|---|---|
|
1 liter = 10-3 m3 = 1 dm3 = 1.0567 quarts |
0 K = -273.15o C = -459.67o F |
|
1 gallon = 4 quarts = 8 pints = 3.7854 liters |
K = oC + 273.15 |
|
1 quart = 32 fluid ounces = 0.94633 liter |
oC = 5/9 (oF - 32) |
|
|
oF = 9/5(oC) + 32 |

|---|---|
|
1 joule = 1kg m2 s-2 = 0.23901 calorie = 9.4781 x 10-4 btu (British thermal unit) |
1 atmosphere = 101.325 kilopascals = 760 torr (mm Hg) = 14.70 pounds per square inch (psi) |
|
1 calorie = 4.184 joules = 3.965 x 10-3 btu |
1 pascal = 1 N m-2 = 1 kg m-1 s-2 |
|
1 btu = 1055.06 joules = 252.2 calories |
1 bar = 10 5 pascals |
|
1 hartree = 4.3597482 x 10-18 J = 627.5095 kcal mol-1 = 27.2116 eV | |
|
1 electron volt (eV) = 23.06037 kcal mol-1 |
