Conversions
An electric resistance converter expresses one resistance across the SI ohm family and the historical CGS resistance units that still appear in older electrical references. It is useful when a value starts in microohms, kilohms, or megaohms but you want to see the same magnitude across circuit, wiring, insulation, and legacy-unit scales without converting by hand.
This page converts a non-negative resistance across microohms, milliohms, ohms, kilohms, megaohms, gigaohms, abohms, and statohms.
That makes it useful for both practical resistor and wiring work and for interpreting historical resistance units that are not part of today's standard SI workflow.
The converter first resolves the entered value into ohms. Every supporting result is then just the same resistance written at another SI scale or in one of the CGS reference systems.
Keeping the ohm baseline visible is especially useful when you move between very small shunt or conductor values and much larger bias or insulation values.
1 mΩ = 10^-3 Ω; 1 µΩ = 10^-6 Ω
Small conductor and shunt values often read more naturally in milliohms or microohms.
1 kΩ = 1,000 Ω; 1 MΩ = 1,000,000 Ω; 1 GΩ = 1,000,000,000 Ω
Larger SI prefixes are common for resistor networks, sensing, and insulation checks.
1 abΩ = 10^-9 Ω; 1 statΩ ≈ 8.9875517923 × 10^11 Ω
The historical CGS units are included so older references can be compared directly against the modern ohm baseline.
The SI section is the practical reference for modern circuit work because it spans the range from microohm shunts through gigaohm insulation values. The CGS section is there mainly to keep older electrostatic and electromagnetic references legible when they use abohms or statohms.
Highlighting the source unit inside the result sheet makes it easier to confirm the conversion path when you move between very different scales.
This calculator does not estimate current, voltage drop, power dissipation, thermal drift, tolerance spread, or material resistivity. It converts one resistance quantity into equivalent unit expressions only.
Use it as a reference and planning aid. If the next question is about circuit behaviour or conductor performance, switch to a calculator that models those relationships directly.
Frequently asked questions
Because electrical work spans a very wide resistance range. Shunts, conductors, and contact paths can live in microohms or milliohms, while bias networks and insulation checks can live in megaohms or gigaohms.
They are historical CGS-system resistance units. They are not standard for modern circuit work, but they still appear in older electrical and electrostatics references.
No. Voltage drop depends on current as well as resistance. This page only converts the resistance quantity itself between units.
