About Converting Centiamperes to Microamperes
Centiampere and Microampere 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: Centiampere is 0.01 ampere units, and microampere is 0.000001 ampere units.
Formula
microamperes = centiamperes × 10000
This factor comes from each unit's defined relationship to the category's base unit: 1 centiampere equals 0.01 base units, and 1 microampere equals 0.000001 base units, so dividing one by the other gives the direct centiampere-to-microampere factor of 10000.
Simple example
1 cA × 10000 = 10,000 uA
1 centiampere = 10,000 microamperes.
Real-world example
120 cA × 10000 = 1,200,000 uA
120 centiamperes = 1,200,000 microamperes.

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

Frequently asked questions
How many microamperes are in 1 centiampere?
1 centiampere equals 10,000 microamperes, using the exact defined conversion factor rather than an estimate.
How do I convert centiampere to microampere?
Multiply the centiampere value by 10000. The converter above does this instantly to whatever precision you set.
How do I convert microampere back to centiampere?
Use the reverse factor: 1 microampere equals 0.0001 centiamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a centiampere?
Centiampere (cA) is a unit of electricity.
What is a microampere?
Microampere (uA) is a unit of electricity.
Is the centiampere to microampere conversion exact?
Yes. Both centiampere and microampere are defined by fixed standards rather than physical artifacts, so the factor of 10000 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.
