In the table below you can find the conversions constant of the
measuring units (e.g. metric conversions) most commonly used in the
scientific field, mostly between (but not limited to) Imperaial/USA and
international (SI)/common units measurement systems. We tried to focus
just on the science-related units, avoiding less interesting unit
conversions like old roman or greek. If you have any suggestions about
new measuring units, or corrections on the constants reported, please
