Current converter
Convert between microamps, milliamps, amps and kiloamps, and see what draws that much in the real world.
That's 25× as much current as an LED, while fast phone charging is 4× more. At 230 V that carries about 115 watts.
What it means
What draws that much?
Household power is shown at 230 V. At 120 V the same current delivers about half the watts.

Three things worth knowing
-
Watts = volts × amps
A 2,300 W kettle on 230 V draws 10 amps. Rearranged, this tells you what fuse a device needs.
-
Ampère and the two wires
André-Marie Ampère showed that two wires carrying current attract or repel each other. The amp was defined by that force until 2019, when it moved to the elementary charge.

The device decides the current
A 3 A charger does not force 3 A into your phone; it offers up to 3 A. The phone takes what it needs, which is why a bigger charger is safe.

Background
About current units
Current is the rate charge flows, measured in amps: one coulomb per second. Electronics lives in milliamps, appliances in amps, and lightning in kiloamps.
