How the formula works
Both hectoampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectoamperes by 1.000000e+20 to get attoamperes. To reverse the conversion, multiply a attoampere value by 1.000000e-20 to get back to hectoamperes.
Frequently asked questions
What is Hectoampere (hA)?
A Hectoampere (hA) equals 100 ampere(s), a scaled unit of electric current used for hecto-scale electrical work.
What is Attoampere (aA)?
An Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
How do I convert hectoamperes to attoamperes?
Multiply the hectoampere value by 1.000000e+20 to get the equivalent in attoamperes. For example, 5 hA × 1.000000e+20 = 5.000000e+20 aA.
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 attoamperes back to hectoamperes?
Yes. Divide the attoampere value by 1.000000e+20, or multiply it by 1.000000e-20, to get hectoamperes.
