How to convert milliamperes to microamperes
One ampere is one coulomb per second. Converting units does not change RMS, peak, or average current conventions; compare measurements made on the same basis.
Use x for the value in mA, b for the intermediate value in A, and y for the result in µA.
µA = mA × 0.001 ÷ 0.000001
Worked examples
10 mA ≈ 10000 µA
Step 1: (10 × 0.001) ≈ 0.01 A.
Step 2: 0.01 ÷ 0.000001 ≈ 10000 µA.20 mA ≈ 20000 µA
Step 1: (20 × 0.001) ≈ 0.02 A.
Step 2: 0.02 ÷ 0.000001 ≈ 20000 µA.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Milliamperes
Milliamperes (mA) measures current under the conventions above. The base value in A is (x × 0.001), where x is the numerical value in mA. Factors shown here are rounded for display; calculations use the stored factor.
About Microamperes
Microamperes (µA) measures current under the conventions above. The base value in A is (x × 0.000001), where x is the numerical value in µA. Factors shown here are rounded for display; calculations use the stored factor.
