Frequently Asked Questions
Is this tool really free?
▼
Yes, completely free with no limits and no sign-up. Everything runs in your browser.
Is my data sent to a server?
▼
No. All conversion math happens directly in your browser. Nothing you type is ever sent anywhere.
What units are supported?
▼
8 units: Ampere, Milliampere, Microampere, Nanoampere, Kiloampere, Abampere, Statampere, and Biot.
What is an Ampere?
▼
The ampere (A) is the standard unit of electric current. One ampere is one coulomb of charge flowing per second. It is the base unit used in everyday electrical measurements.
What is a Milliampere?
▼
A milliampere (mA) is one thousandth of an ampere. It is commonly used for measuring the current drawn by small electronic devices, sensors, and LEDs.
What is a Microampere?
▼
A microampere is one millionth of an ampere. It is used for very low-current measurements in electronics, medical devices, and scientific instruments.
What is an Abampere?
▼
An abampere is 10 amperes. It is a unit from the older CGS electromagnetic system, still found in some physics and engineering references.
What is a Statampere?
▼
A statampere is a very small current unit from the CGS electrostatic system. It equals about 3.336 x 10 to the minus 10 amperes.
How accurate are the conversions?
▼
The tool uses standard conversion factors and displays up to 10 significant figures.
Does it update instantly?
▼
Yes. All results recalculate as soon as you change any input.
What Is Electric Current Converter?
Electric Current Converter is a free tool that converts between 8 electric current units right in your browser. It covers the practical ampere scale (nanoampere through kiloampere) and the historical CGS units (abampere, statampere, biot). Nothing you type is ever sent anywhere - all math runs locally on your device.
The result updates live as you type, and a full conversion table shows the same current in every other unit at once. Use the swap button to flip your units instantly, or copy the result to your clipboard in one click.

Tips for Best Results
Metric prefixes for current
1 A = 1,000 mA = 1,000,000 uA = 1,000,000,000 nA. Each step is a factor of 1,000.
Common current values
A typical LED draws 20 mA. A USB port provides up to 500 mA (USB 2.0) or 900 mA (USB 3.0). A household circuit breaker is 15 or 20 A.
Kiloampere for industrial power
Kiloamperes are used for large industrial systems, welding machines, and power grid fault currents.
Abampere is 10 amperes
The abampere is a CGS unit equal to exactly 10 amperes. It appears in older physics and engineering texts.
Statampere is extremely small
One statampere is about 3.336 x 10 to the minus 10 amperes. It is a CGS electrostatic unit rarely used outside theoretical physics.
