Description: Electric Resistance Unit Converter

The Electric Resistance Unit Converter is a practical tool designed to assist in the conversion between various units used to measure electric resistance. Electric resistance represents the opposition to the flow of electric current in a material. This converter enables users to seamlessly switch between different units of electric resistance, aiding in calculations and comparisons in fields such as electrical engineering, electronics, and physics.

Formula:The formula to calculate electric resistance (RR) is based on Ohm's Law, which states that resistance is equal to the ratio of voltage (VV) across a conductor to the current (II) flowing through it:R=VIR = \frac{V}{I}Where:

  • RR is the electric resistance,
  • VV is the voltage, and
  • II is the current.

How to Convert:To convert between different units of electric resistance, follow these steps:

  1. Determine the Initial and Target Units: Identify the unit you have and the unit you want to convert to.

  2. Find Conversion Factors: Use conversion factors to convert between units. These conversion factors are based on the relationships between the units.

  3. Apply the Conversion Factor: Multiply the value you want to convert by the appropriate conversion factor. If you're converting from larger units to smaller units, you'll multiply. If you're converting from smaller units to larger units, you'll divide.

  4. Perform the Calculation: Apply the conversion factor to the value you want to convert to get the equivalent value in the desired unit.

Units Explanation:

  1. Ohm [Ω]: Electric resistance expressed in ohms, the standard SI unit used to measure resistance.
  2. Megohm [MΩ]: Electric resistance expressed in megohms, equal to one million ohms.
  3. Microhm [μΩ]: Electric resistance expressed in microhms, equal to one millionth of an ohm.
  4. Volt/Ampere [V/A]: Electric resistance expressed in volts per ampere, representing the ratio of voltage to current and is equivalent to ohms.
  5. Reciprocal Siemens [1/S]: Electric resistance expressed in reciprocal siemens, where siemens is the unit of conductance, and the reciprocal of conductance is resistance.
  6. Abohm [abΩ]: Electric resistance expressed in abohms, a unit used in the CGS electromagnetic unit system.
  7. EMU of Resistance: Electromagnetic unit of resistance, used in the CGS electromagnetic unit system.
  8. Statohm [stΩ]: Electric resistance expressed in statohms, a unit used in the CGS electromagnetic unit system.
  9. ESU of Resistance: Electrostatic unit of resistance, used in the CGS electrostatic unit system.
  10. Quantized Hall Resistance: Resistance in the quantum Hall effect, characterized by the Hall resistance quantum (RHR_H) equal to h/e2h/e^2, where hh is the Planck constant and ee is the elementary charge.

Understanding these units and the conversion process allows for precise measurement and manipulation of electric resistance across different scales and applications.


  1. Conversion from Ohm [Ω] to Megohm [MΩ]:1Ohm=106Megohm1\, \text{Ohm} = 10^{-6}\, \text{Megohm}To convert 500 ohms to megohms:500Ohm×106=0.0005Megohm500\, \text{Ohm} \times 10^{-6} = 0.0005\, \text{Megohm}

  2. Conversion from Volt/Ampere [V/A] to Ohm [Ω]:1Volt/Ampere=1Ohm1\, \text{Volt/Ampere} = 1\, \text{Ohm}To convert 2 volts per ampere to ohms:2Volt/Ampere×1=2Ohms2\, \text{Volt/Ampere} \times 1 = 2\, \text{Ohms}

By following these steps and using appropriate conversion factors, electric resistance values can be accurately converted between different units.
