Resistance Conversions

The unit of electrical electrical resistance is the ohm. It is named after named after Georg Simon Ohm.

One volt of direct current applied across one ohm of resistance causes one ampere of current to flow, and one watt of power to be dissipated across the resistor.





Standard unit = Ohm (Ω)

  abohm ohm statohm
1 ab Ω =1 10-9 1.113 * 10-
1 stat Ω =109 1 1.113 * 10-12
1 stat Ω = 8.987 * 1020 8.987 * 1011 1

Note: The prefix "ab" is used to indicate an electromagnetic unit in the centimeter-gram-second system.
          The  prefix "stat" is used to indicate an electrical unit in the electrostatic centimeter-gram-second system of units.
