How the formula works
Both centiohm and rontoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiohms by 1.000000e+25 to get rontoohms. To reverse the conversion, multiply a rontoohm value by 1.000000e-25 to get back to centiohms.
Frequently asked questions
What is Centiohm (cΩ)?
A Centiohm (cΩ) equals 1/100 ohm(s), a scaled unit of electrical resistance used for centi-scale electrical work.
What is Rontoohm (rΩ)?
A Rontoohm (rΩ) equals 1e-27 ohm(s), a scaled unit of electrical resistance used for ronto-scale electrical work.
How do I convert centiohms to rontoohms?
Multiply the centiohm value by 1.000000e+25 to get the equivalent in rontoohms. For example, 5 cΩ × 1.000000e+25 = 5.000000e+25 rΩ.
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 rontoohms back to centiohms?
Yes. Divide the rontoohm value by 1.000000e+25, or multiply it by 1.000000e-25, to get centiohms.
