📐 How to Use

  1. Set the From dropdown to the current unit you are reading, for example milliampere, and the To dropdown to the one you want.
  2. Enter the current in the value field; the converted figure appears live with its unit symbol beside it.
  3. Use the swap button when you need the reverse direction, then Copy to paste the number into your notes or calculation.
  4. Open a pair from the Common Electric Current Conversions grid, or follow any All Electric Current Conversions link to a page with its own converter and conversion table.

❓ Frequently Asked Questions

QHow many mA are in 1 A?
1 A is 1000 mA. Pushing further down the same prefix chain, 1 A is 1,000,000 µA and 1,000,000,000 nA, so a 20 mA sensor loop is 0.02 A and a 500 µA bias current is half a milliamp.
QWhat is 1 mA in microamperes?
1 mA equals 1000 µA. Each step between milli, micro and nano is a factor of a thousand, which is why a datasheet quoting 250 µA of quiescent draw is describing a quarter of a milliamp.
QDoes this converter apply Ohm's law?
No. It restates one current value in another current unit and nothing more. Ohm's law ties together three distinct quantities, so volts and ohms belong to the separate voltage and resistance converters on this site.
QWhat is an abampere?
An abampere is 10 amperes, the current unit of the CGS electromagnetic system. Its electrostatic counterpart, the statampere, is about 3.33564e-10 A. Both turn up in older physics literature and are kept here so historic figures can be read in modern units.

ℹ️ About Electric Current Conversion

Electric current is the rate at which charge flows past a point, and one ampere is one coulomb per second. Since the 2019 revision of the SI, the ampere is defined by fixing the elementary charge rather than by a force between wires. Most entries here are decimal prefixes on the ampere, spanning the nanoamps of sensor leakage to the kiloamps of a fault current. The outliers come from the older CGS systems: the abampere of the electromagnetic set and the statampere of the electrostatic set, whose size is tied to the speed of light.

Seven units are supported, with the ampere as the quantity that everything is referred to. Results print four decimals at ten and above, six between one and ten, and eight below one, trailing zeros stripped. All of it runs client side once the page has loaded.

📏 7 Supported Units

Statampere (statA), Nanoampere (nA), Microampere (µA), Milliampere (mA), Ampere (A), Abampere (abA), Kiloampere (kA).
