What it is Filled
A unit of power equal to one thousand watts, an SI derived unit used to rate electric motors, generators, heaters, vehicles and appliances, to express the output of power plants together with the megawatt, and, as kilowatt thermal, to distinguish heat output from electrical output; the kilowatt-hour, the energy delivered by one kilowatt over one hour, is the unit in which electricity is metered and sold.
Why it exists Filled
Let an agent explain the kilowatt and its relation to the watt, kilowatt-hour and other power units, support conversions and calculations, describe its use in ratings and energy billing, and address common confusions between power and energy.
Distinguishing features Filled
- SI derived
- Decimal multiple
- Power not energy
- Thermal and electrical variants
What robots and AI may and may not do Filled
Must not
- Confuse kilowatts with kilowatt-hours in bills or energy reports.
- Run equipment above its rated power or overload circuits.
- Misstate a product's rated power in labels or listings.
- Present peak power as continuous rating.
Only with a human decision
- Changing loads on an electrical installation near its capacity.
May
- Convert kilowatts to other power units and explain kilowatts versus kilowatt-hours.
- Report the power rating or draw of equipment it is authorized to monitor.
Moral aspects Filled
- Misunderstood power ratings lead to overloaded circuits and fires.
- Energy bills based on confused units can mislead households.
Who is affected
- Households and bill payers
- Electricians
- Equipment users
Owners Filled
Steward
Nobody: an SI derived unit maintained by the international metrology system.
