How to Convert Milliamperes to Microamperes
To convert milliamperes to microamperes, multiply the electric current by the following conversion ratio: 1,000 microamperes/milliampere.
Since one milliampere is equal to 1,000 microamperes, you can use this simple formula to convert:
The electric current in microamperes is equal to the electric current in milliamperes multiplied by 1,000.
For example, here's how to convert 5 milliamperes to microamperes using the formula above.
How Many Microamperes Are in a Milliampere?
There are 1,000 microamperes in a milliampere, which is why we use this value in the formula above.
Our milliampere to microampere calculator automatically converts your electric current measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Milliamperes and microamperes are both units used to measure electric current. Keep reading to learn more about each unit.
What Is a Milliampere?
A milliampere is a unit of electric current equal to 1/1,000 of an ampere (0.001 A). One-thousandth of an Ampere (0.001 A). [1]
The milliampere is classified as a metric and SI-compatible unit of electric current. Milliamperes can be abbreviated as mA; for example, 1 milliampere can be written as 1 mA.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliampere (mA) a convenient decimal multiple of the ampere (A).
In practice, milliamperes (mA) are widely used across fine-tolerance laboratory, analytical, and micro-scale electric current measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Microampere?
A microampere is a unit of electric current equal to 1/1,000,000 of an ampere (0.000001 A). One-millionth of an Ampere (10⁻⁶ A). [2]
The microampere is classified as a metric and SI-compatible unit of electric current. Microamperes can be abbreviated as µA; for example, 1 microampere can be written as 1 µA.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microampere (µA) a convenient decimal multiple of the ampere (A).
In practice, microamperes (µA) are widely used across fine-tolerance laboratory, analytical, and micro-scale electric current measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting electric current between milliamperes (mA) and microamperes (µA), keep full floating-point precision (1 mA = 1,000 µA; 1 µA = 0.001 mA) during intermediate calculations and round only the final microampere figure to match your instrument tolerance.
