Milliampere to Microampere Converter
Convert milliamperes to microamperes (mA to µA) instantly with this free online electric-current converter. Enter any value in the Milliampere field and get the equivalent in Microampere immediately. This converter handles any quantity — from tiny fractions to large numbers — with full precision. No signup, no ads in the widget, and the conversion runs entirely in your browser for instant results.
The conversion factor is exact: 1 mA = 1000 µA. To convert milliamperes to microamperes, multiply your Milliampere value by 1000. For example, 10 mA = 10000 µA. You can also reverse the calculation: 1 µA = 0.001 mA.

Formula
Milliampere to Microampere conversion: 1 mA = 1000 µA microamperes = milliamperes × 1000 1 µA = 0.001 mA milliamperes = microamperes × 0.001
Example
Example: Convert 10 mA to µA: 10 mA × 1000 = 10000 µA So, 10 mA is about 10000 µA. To convert back, multiply by 0.001: 10000 µA × 0.001 = 10 mA.

Frequently Asked Questions
How do I convert milliamperes to microamperes?
Enter the value in Milliampere (mA) in the 'From' field. The equivalent in Microampere (µA) appears instantly in the 'To' field. The converter uses precise conversion factors and updates in real time as you type.
What is the formula to convert mA to µA?
1 mA = 1000 µA, so microamperes = milliamperes × 1000. To convert back, 1 µA = 0.001 mA. The full formula and a worked example are shown on this page.
How many microamperes are in one Milliampere?
1 mA = 1000 µA.
Is this Milliampere to Microampere converter free?
Yes, completely free with no signup, no limits, and no ads in the converter widget. You can convert as many values as you need. The tool runs entirely in your browser, so your data never leaves your device.
Can I convert microamperes back to milliamperes?
Yes. Click the 'Swap Units' button to reverse the direction. You can also use the dropdown menus to select any other electric-current unit for either field.
How accurate is the mA to µA conversion?
The converter uses high-precision conversion factors (up to 8 decimal places). Results are displayed with up to 6 decimal places, with trailing zeros removed for readability. For scientific or engineering work, always verify with official standards.
