How the formula works
Both rontoohm and microohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoohms by 1.000000e-21 to get microohms. To reverse the conversion, multiply a microohm value by 1.000000e+21 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 Microohm (uΩ)?
A Microohm (uΩ) equals 1e-06 ohm(s), a scaled unit of electrical resistance used for micro-scale electrical work.
How do I convert rontoohms to microohms?
Multiply the rontoohm value by 1.000000e-21 to get the equivalent in microohms. For example, 5 rΩ × 1.000000e-21 = 5.000000e-21 uΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert microohms back to rontoohms?
Yes. Divide the microohm value by 1.000000e-21, or multiply it by 1.000000e+21, to get rontoohms.
