Milliohms to zeptoohms converter
Convert milliohms (mΩ) to zeptoohms (zΩ). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in mΩ; the result is in zΩ.
Formula
Worked example
Convert 1 mΩ to zΩ:
1 mΩ ≈ 1e+18 zΩ
Multiply your mΩ value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What milliohms measure
Milliohms (mΩ) represent electrical resistance. One unit equals 10^-3 Ω. One ohm corresponds to one volt per ampere for electrical resistance.
Reading the result in zeptoohms
Zeptoohms (zΩ) represent electrical resistance. One unit equals 10^-21 Ω. One ohm corresponds to one volt per ampere for electrical resistance.
Where this conversion helps
Normalize resistor values or measured electrical resistance into a common scale. Resistance is not resistivity, which also depends on geometry. A DC resistance is not necessarily an AC impedance.
How the scale changes
The input unit has a factor of 1e-3 Ω; the output unit has a factor of 1e-21 Ω. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
