How the formula works
Both ohm and centiohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ohms by 100 to get centiohms. To reverse the conversion, multiply a centiohm value by 0.01 to get back to ohms.
Frequently asked questions
What is Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
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 ohms to centiohms?
Multiply the ohm value by 100 to get the equivalent in centiohms. For example, 5 Ω × 100 = 500 cΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 100 is an exact, non-rounded value.
Can I convert centiohms back to ohms?
Yes. Divide the centiohm value by 100, or multiply it by 0.01, to get ohms.
