Use the Electric Current Converter
Electric Current formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in A.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (A) |
Electric Current examples
A to mA
10 A = 10,000 mA.
A to µA
10 A = 10,000,000 µA.
A to kA
10 A = 0.01 kA.
How to calculate Electric Current step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Electric Current result
The ampere is the SI unit of electric current and equals one coulomb per second. A milliampere is one thousandth of an ampere and a microampere one millionth. Household appliances draw amperes, while electronics often work in milliamperes and microamperes.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 A |
|---|---|---|---|
| Ampere | A | 1 A = 1 A | 1 A |
| Kiloampere | kA | 1 kA = 1,000 A | 0.001 kA |
| Milliampere | mA | 1 mA = 0.001 A | 1,000 mA |
| Microampere | µA | 1 µA = 0.000001 A | 1,000,000 µA |
| Nanoampere | nA | 1 nA = 1×10⁻⁹ A | 1,000,000,000 nA |
| Abampere (biot) | abA | 1 abA = 10 A | 0.1 abA |
| Statampere | statA | 1 statA = 3.335641×10⁻¹⁰ A | 2,997,925,000 statA |
Common mistakes when calculating Electric Current
- Mixing mA and µA, which differ by 1,000.
- Confusing current (A) with charge (C or Ah).
- Forgetting that kA is 1,000 A.
Electric Current FAQ
How many mA is 1 A?
1 A is 1,000 mA.
How many µA is 1 mA?
1 mA is 1,000 µA.
What is an ampere?
The SI unit of current: a flow of one coulomb of charge per second.
What is the base unit for electric current?
This converter uses ampere (A) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two electric current units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many milliamperes are in 1 ampere?
1 A = 1,000 mA.
How many microamperes are in 1 ampere?
1 A = 1,000,000 µA.
How many kiloamperes are in 1 ampere?
1 A = 0.001 kA.
Which electric current units does this converter support?
It covers 7 units: ampere (A), kiloampere (kA), milliampere (mA), microampere (µA), nanoampere (nA), abampere (abA), statampere (statA).
How accurate is the electric current converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
