Difference Between Kilowatt and Amps
What is Kilowatt (kW)?
A kilowatt is a unit of power that measures the rate at which energy is consumed or generated.
It calculates the real work performed or energy converted each second.
A kilowatt is equal to 1,000 watts and is often used to measure the power output of machinery, motors, appliances & electrical systems.
Ex: 2 kW heater uses 2 kilojoules of energy each second.
What is Ampere (A)?
An ampere, or “amp,” is a unit of electric current. It measures the movement of an electric charge (electrons) across a conductor. One ampere represents one coulomb of charge flowing per second in a circuit.
Amps show the current carrying capacity of cables, breakers & devices ensuring that they operate safely and without overheating.

Difference between Kilowatt and Amps
| Kilowatt (kW) | Ampere (A) |
|---|---|
| Kilowatt measures power or the rate of energy usage. | Ampere measures electric current or flow of charge. |
| It indicates how much energy a device consumes or delivers. | It indicates how much current flows through a conductor. |
| Dependent on both voltage and current (kW = V × I × PF ÷ 1000). | Dependent only on voltage and power consumed (I = P ÷ V). |
| Commonly used to rate motors, heaters, and appliances. | Commonly used to size cables, breakers, and protection devices. |
| Expressed in units of watts or kilowatts. | Expressed in units of amperes (A). |
