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 = c^{2} abohms = 8.987551787x10^{20} 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 = 8.987551787x10^{11} ohms^{[3]}^{[4]}
