How the formula works
Both ohm and deciohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ohms by 10 to get deciohms. To reverse the conversion, multiply a deciohm value by 0.1 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 Deciohm (dΩ)?
A Deciohm (dΩ) equals 1/10 ohm(s), a scaled unit of electrical resistance used for deci-scale electrical work.
How do I convert ohms to deciohms?
Multiply the ohm value by 10 to get the equivalent in deciohms. For example, 5 Ω × 10 = 50 dΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 10 is an exact, non-rounded value.
Can I convert deciohms back to ohms?
Yes. Divide the deciohm value by 10, or multiply it by 0.1, to get ohms.
