How the formula works
Both hectoohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectoohms by 1.000000e+20 to get attoohms. To reverse the conversion, multiply a attoohm value by 1.000000e-20 to get back to hectoohms.
Frequently asked questions
What is Hectoohm (hΩ)?
A Hectoohm (hΩ) equals 100 ohm(s), a scaled unit of electrical resistance used for hecto-scale electrical work.
What is Attoohm (aΩ)?
An Attoohm (aΩ) equals 1e-18 ohm(s), a scaled unit of electrical resistance used for atto-scale electrical work.
How do I convert hectoohms to attoohms?
Multiply the hectoohm value by 1.000000e+20 to get the equivalent in attoohms. For example, 5 hΩ × 1.000000e+20 = 5.000000e+20 aΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+20 is an exact, non-rounded value.
Can I convert attoohms back to hectoohms?
Yes. Divide the attoohm value by 1.000000e+20, or multiply it by 1.000000e-20, to get hectoohms.
