How the formula works
Both kiloohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kiloohms by 1.000000e+21 to get attoohms. To reverse the conversion, multiply a attoohm value by 1.000000e-21 to get back to kiloohms.
Frequently asked questions
What is Kiloohm (kΩ)?
A Kiloohm (kΩ) equals 1,000 ohm(s), a scaled unit of electrical resistance used for kilo-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 kiloohms to attoohms?
Multiply the kiloohm value by 1.000000e+21 to get the equivalent in attoohms. For example, 5 kΩ × 1.000000e+21 = 5.000000e+21 aΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+21 is an exact, non-rounded value.
Can I convert attoohms back to kiloohms?
Yes. Divide the attoohm value by 1.000000e+21, or multiply it by 1.000000e-21, to get kiloohms.
