The statohm is the unit of electrical resistance in the electrostatic system of units which was part of the CGS system of units based upon the centimetre, gram and second.[1]
The static units in that system were related to the equivalent electromagnetic units by a factor of the speed of light. Those units were known as absolute units and so the equivalent of the statohm was the abohm and their proportions were:
1 statohm = c2 abohms = 8.987551787x1020 abohms where c is the speed of light in centimetres per second.
These units are not common now. The SI unit of resistance is the ohm. The statohm is nearly a trillion times larger than the ohm and is the largest unit of resistance ever used in any measurement system.[2] The statohm as a practical unit is as unusably large as the abohm is unusably small.
1 statohm = 8.987551787x1011 ohms[3][4]
