Electric Current Converter

Electric current is the flow of charge, measured in amperes. Battery capacity and device draw are usually in milliamperes, sensor and leakage currents in microamperes, and fault or lightning currents in kiloamperes. This converter handles the SI prefixes and the CGS units still found in older physics texts.

How to use Electric Current Converter

1. Type the value you want to convert.
2. Choose the unit you have in From and the unit you want in To. The swap button turns the conversion round.
3. Read the answer, with the formula underneath. For example, 1,500 mA = 1.5 A.
4. Open All units to see the value in every unit at once, and copy the one you need.

When it comes in handy

• Reading USB, charger and battery specifications.
• Electronics calculations with small currents.
• Physics homework.

Frequently asked questions

Is mAh a unit of current?

No, mAh (milliamp-hours) is charge, current × time. A 3,000 mAh battery could supply 3,000 mA for one hour or 300 mA for ten hours, in theory.

What is an abampere?

The CGS electromagnetic unit of current, equal to 10 A. It is also called a biot.
