amps to microamps | Exact Decimal + Formula
1 Ampere = 1000000 Microampere
One ampere equals exactly a million microamperes. Real-world use: household circuit ratings (15/20 a), charger output, and appliance specs. This page expresses those values in microamperes, which is used for sleep-mode electronics, sensors, and biomedical devices. Use the calculator above, then check the reference table for common values from 0.001 to 1000.
