Kilowatt (kW)

The kilowatt (symbol: kW) is a unit of power in the International System of Units (SI) equal to 1,000 watts:

Kilowatts are widely used to measure the power consumption or output of household appliances, small engines, and electric tools. For example, a typical microwave oven might use about 1 kW of power.

In electricity billing, power usage is often measured in kilowatt-hours (kWh), which reflects energy consumption over time.

The kilowatt is a practical unit for everyday energy use, bridging the scale from watts (for small devices) to megawatts (for larger power generation). It helps people understand and compare the power ratings of common electrical equipment.

Volt-Ampere [V·A]

The volt-ampere (VA) is a unit of apparent power in an electrical circuit, especially in alternating current (AC) systems.

• 
  

  It is the product of the root-mean-square (RMS) voltage (in volts, V) and current (in amperes, A).

  
  
• 
  

  Apparent power (VA) combines both real power (measured in watts, W) and reactive power (measured in volt-amperes reactive, VAR), but does not account for the phase difference between voltage and current.

  
  
• 
  

  Unlike watts, volt-amperes do not represent the actual usable power but the total power flowing in the circuit.

  
  

Volt-amperes are commonly used to rate electrical devices like transformers and uninterruptible power supplies (UPS), indicating their maximum power capacity.
