How the formula works
Both milliohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliohms by 1.000000e+15 to get attoohms. To reverse the conversion, multiply a attoohm value by 1.000000e-15 to get back to milliohms.
Frequently asked questions
What is Milliohm (mΩ)?
A Milliohm (mΩ) equals 1/1,000 ohm(s), a scaled unit of electrical resistance used for milli-scale electrical work.
What is Attoohm (aΩ)?
An Attoohm (aΩ) equals 1e-18 ohm(s), a scaled unit of electrical resistance used for atto-scale electrical work.
How do I convert milliohms to attoohms?
Multiply the milliohm value by 1.000000e+15 to get the equivalent in attoohms. For example, 5 mΩ × 1.000000e+15 = 5.000000e+15 aΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+15 is an exact, non-rounded value.
Can I convert attoohms back to milliohms?
Yes. Divide the attoohm value by 1.000000e+15, or multiply it by 1.000000e-15, to get milliohms.
