How the formula works
Both milliampere and deciampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliamperes by 0.01 to get deciamperes. To reverse the conversion, multiply a deciampere value by 100 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 Deciampere (dA)?
A Deciampere (dA) equals 1/10 ampere(s), a scaled unit of electric current used for deci-scale electrical work.
How do I convert milliamperes to deciamperes?
Multiply the milliampere value by 0.01 to get the equivalent in deciamperes. For example, 5 mA × 0.01 = 0.05 dA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.01 is an exact, non-rounded value.
Can I convert deciamperes back to milliamperes?
Yes. Divide the deciampere value by 0.01, or multiply it by 100, to get milliamperes.
