Context values
Some unit families need one extra value for a physically accurate result.
Milliampere is 0.001 ampere units.
Result = input x 0.1 / 0.001.

About Converting Deciamperes to Milliamperes
Deciampere and Milliampere 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: Deciampere is 0.1 ampere units, and milliampere is 0.001 ampere units.
Formula
milliamperes = deciamperes × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 deciampere equals 0.1 base units, and 1 milliampere equals 0.001 base units, so dividing one by the other gives the direct deciampere-to-milliampere factor of 100.
Simple example
1 dA × 100 = 100 mA
1 deciampere = 100 milliamperes.
Real-world example
120 dA × 100 = 12,000 mA
120 deciamperes = 12,000 milliamperes.

Reverse conversion: Milliampere to Deciampere
100 mA × 0.01 = 1 dA
100 milliamperes = 1 deciampere.
deciamperes = milliamperes × 0.01

Frequently asked questions
How many milliamperes are in 1 deciampere?
1 deciampere equals 100 milliamperes, using the exact defined conversion factor rather than an estimate.
How do I convert deciampere to milliampere?
Multiply the deciampere value by 100. The converter above does this instantly to whatever precision you set.
How do I convert milliampere back to deciampere?
Use the reverse factor: 1 milliampere equals 0.01 deciamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciampere?
Deciampere (dA) is a unit of electricity.
What is a milliampere?
Milliampere (mA) is a unit of electricity.
Is the deciampere to milliampere conversion exact?
Yes. Both deciampere and milliampere are defined by fixed standards rather than physical artifacts, so the factor of 100 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.
