Milliamperes to Amperes Converter
1 milliampere = 0.001 amperes
1 milliampere equals 0.001 amperes
How to convert milliamperes to amperes
Milli means one thousandth and micro means one millionth of an ampere. Changing the unit does not convert an AC peak reading to RMS or an average reading; preserve the measurement convention.
A = mA × 0.001One milliampere is 0.001 amperes, so a single multiplication converts any value.
0.01 A = 10 × 0.001Milliamperes to amperes conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
