Jacobian oxyhydrogen unit
The Jacobian oxyhydrogen unit was a unit of measurement for electrical current that was customary in Germany until around 1900 and was named after Moritz Hermann von Jacobi , who defined it. This was a purely empirical unit based on the electrolytic separation of oxyhydrogen gas from water , which does not belong to any system of units . Direct current has the strength of a Jacobian oxyhydrogen unit when one cubic centimeter of oxyhydrogen gas is developed at 0 ° C and 1013.25 mbar air pressure in one minute .
In today's international system of units , one Jacobian oxyhydrogen unit corresponds to approximately 90 milliamps .
