How the formula works
Both milliampere and nanoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliamperes by 1.000000e+06 to get nanoamperes. To reverse the conversion, multiply a nanoampere value by 0.000001 to get back to milliamperes.
Frequently asked questions
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
What is Nanoampere (nA)?
A Nanoampere (nA) equals 1e-09 ampere(s), a scaled unit of electric current used for nano-scale electrical work.
How do I convert milliamperes to nanoamperes?
Multiply the milliampere value by 1.000000e+06 to get the equivalent in nanoamperes. For example, 5 mA × 1.000000e+06 = 5.000000e+06 nA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert nanoamperes back to milliamperes?
Yes. Divide the nanoampere value by 1.000000e+06, or multiply it by 0.000001, to get milliamperes.
