About Converting Microamperes to Centiamperes
Microampere and Centiampere both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Microampere is 0.000001 ampere units, and centiampere is 0.01 ampere units.
Formula
centiamperes = microamperes × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 microampere equals 0.000001 base units, and 1 centiampere equals 0.01 base units, so dividing one by the other gives the direct microampere-to-centiampere factor of 0.0001.
Simple example
1 uA × 0.0001 = 0.0001 cA
1 microampere = 0.0001 centiamperes.
Real-world example
120 uA × 0.0001 = 0.012 cA
120 microamperes = 0.012 centiamperes.
Conversion table

Reverse conversion: Centiampere to Microampere
0.0001 cA × 10000 = 1 uA
0.0001 centiamperes = 1 microamperes.
microamperes = centiamperes × 10000

Frequently asked questions
How many centiamperes are in 1 microampere?
1 microampere equals 0.0001 centiamperes, using the exact defined conversion factor rather than an estimate.
How do I convert microampere to centiampere?
Multiply the microampere value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert centiampere back to microampere?
Use the reverse factor: 1 centiampere equals 10,000 microamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a microampere?
Microampere (uA) is a unit of electricity.
What is a centiampere?
Centiampere (cA) is a unit of electricity.
Is the microampere to centiampere conversion exact?
Yes. Both microampere and centiampere are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
