Electric Resistance Converter
About the Electric Resistance Converter Tool
Electric resistance is a key concept in electrical engineering, physics, and electronics, describing how much a material opposes the flow of electric current. Measured in ohms (Ω), resistance is essential in applications ranging from power distribution to circuit design. The Electric Resistance Converter Tool simplifies the process of converting between various resistance units, ensuring fast, accurate, and efficient results for professionals and students alike.
This tool handles a wide range of units, from microohms (μΩ) for small resistances to megaohms (MΩ) for high values, supporting common and less familiar units like statohms and abohms. Engineers, electricians, and scientists can use this tool to manage conversions essential in their daily work. Electric resistance, a key variable in Ohm’s Law, governs the relationship between voltage, current, and resistance. Whether you’re troubleshooting a circuit or working on a scientific project, this tool helps streamline complex calculations.
Resistance units vary depending on the measurement system. SI units like ohms (Ω) and megaohms (MΩ) are commonly used, while older units such as abohms (abΩ) and statohms (statΩ) are still seen in certain scientific contexts. Manual conversions between these units can be time-consuming and error-prone. The Electric Resistance Converter Tool automates the conversion process, providing accurate results quickly, ideal for professionals handling precise measurements.
What is Electric Resistance?
Electric resistance is defined as the opposition to the flow of electric current in a material, measured in ohms (Ω). It is the ratio of the applied voltage to the resulting current, and it depends on factors like the material’s length, cross-sectional area, temperature, and resistivity. Materials like copper and aluminum, which offer low resistance, are ideal for wiring, while high-resistance materials such as tungsten are used in heating elements.

Common Units of Electric Resistance and Their Conversion Rates
Below is a table listing commonly used units of electric resistance, including their definitions and conversion rates relative to ohms (Ω), the SI base unit for resistance.
| Unit Name | Symbol | Definition | Conversion Rate (to Ω) |
|---|---|---|---|
| Ohm | Ω | The SI unit of electric resistance. | 1 Ω |
| Megaohm | MΩ | One million ohms, used for high resistance. | 1 MΩ = 1,000,000 Ω |
| Microohm | μΩ | One millionth of an ohm, used for very small resistances. | 1 μΩ = 0.000001 Ω |
| Volt/Ampere | V/A | Equivalent to one ohm. | 1 V/A = 1 Ω |
| Reciprocal Siemens | 1/S | Equivalent to one ohm (inverse of conductance). | 1 S-1 = 1 Ω |
| Abohm | abΩ | CGS unit of resistance, smaller than ohms. | 1 abΩ = 1e-9 Ω |
| Statohm | statΩ | Electrostatic unit, much larger than an ohm. | 1 statΩ = 8.987551787e11 Ω |
| Quantized Hall Resistance | N/A | Resistance observed in the quantum Hall effect. | 1 unit = 25812.80745 Ω |
