How the formula works
Both rontoohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoohms by 1.000000e-09 to get attoohms. To reverse the conversion, multiply a attoohm value by 1.000000e+09 to get back to rontoohms.
Frequently asked questions
What is Rontoohm (rΩ)?
A Rontoohm (rΩ) equals 1e-27 ohm(s), a scaled unit of electrical resistance used for ronto-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 rontoohms to attoohms?
Multiply the rontoohm value by 1.000000e-09 to get the equivalent in attoohms. For example, 5 rΩ × 1.000000e-09 = 5.000000e-09 aΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-09 is an exact, non-rounded value.
Can I convert attoohms back to rontoohms?
Yes. Divide the attoohm value by 1.000000e-09, or multiply it by 1.000000e+09, to get rontoohms.
