How to convert amperes to microamperes
µA = A × 1,000,000Multiply the value in amperes by 1,000,000. To go the other way, multiply by 0.000001 (or divide by 1,000,000).
An ampere is larger than a microampere: one ampere contains 1,000,000 microamperes.

About the units
Ampere (A)
The SI base unit of current: 1/(1.602176634 × 10⁻¹⁹) elementary charges per second.
Microampere (µA)
The microampere (µA) is a unit of electric current in the International System of Units (SI). One microampere equals 0.000001 amperes (A).
Frequently asked questions
How many microamperes are in one ampere?
There are 1,000,000 microamperes in one ampere, and this value is exact by definition.
How do I convert amperes to microamperes?
Multiply the number of amperes by 1,000,000. For example, 10 A × 1,000,000 = 10,000,000 µA.
How many amperes are in one microampere?
One microampere equals 0.000001 amperes. That is the reverse factor, 1 ÷ 1,000,000.
What is 10 amperes in microamperes?
10 A = 10,000,000 µA.
Is this A to µA converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
