About the electric resistance converter

Electrical resistance measures how strongly a component opposes the flow of current, with the SI unit being the ohm (Ω). By Ohm’s law, V = I R, so 1 ohm is the resistance that lets 1 A flow under 1 V. Resistors in electronics span microhms (busbars, shunts) to gigaohms (insulation tests). Use this converter to translate between the standard SI prefixes and legacy CGS units like abohm and statohm.

Frequently asked questions

  • What is Ohm’s law?

    V = I R: voltage equals current times resistance. Solve for any one term given the other two.

  • How many ohms is a megohm?

    1 MΩ = 1,000,000 Ω. Insulation resistance specs are usually quoted in megohms or gigaohms.

  • What is the difference between resistance and resistivity?

    Resistance (Ω) is a property of a specific component and depends on geometry. Resistivity (Ω·m) is a material property independent of size.
