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