How the formula works
Both hectoampere and gigaampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectoamperes by 1.000000e-07 to get gigaamperes. To reverse the conversion, multiply a gigaampere value by 1.000000e+07 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 Gigaampere (GA)?
A Gigaampere (GA) equals 1e+9 ampere(s), a scaled unit of electric current used for giga-scale electrical work.
How do I convert hectoamperes to gigaamperes?
Multiply the hectoampere value by 1.000000e-07 to get the equivalent in gigaamperes. For example, 5 hA × 1.000000e-07 = 5.000000e-07 GA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-07 is an exact, non-rounded value.
Can I convert gigaamperes back to hectoamperes?
Yes. Divide the gigaampere value by 1.000000e-07, or multiply it by 1.000000e+07, to get hectoamperes.
