How the formula works
Both rontoohm and centiohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoohms by 1.000000e-25 to get centiohms. To reverse the conversion, multiply a centiohm value by 1.000000e+25 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 Centiohm (cΩ)?
A Centiohm (cΩ) equals 1/100 ohm(s), a scaled unit of electrical resistance used for centi-scale electrical work.
How do I convert rontoohms to centiohms?
Multiply the rontoohm value by 1.000000e-25 to get the equivalent in centiohms. For example, 5 rΩ × 1.000000e-25 = 5.000000e-25 cΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-25 is an exact, non-rounded value.
Can I convert centiohms back to rontoohms?
Yes. Divide the centiohm value by 1.000000e-25, or multiply it by 1.000000e+25, to get rontoohms.
