Power Converter

1 kilowatt (kW) equals 1000 watt (W).

How it works

• Expressed the source unit in watt using its exact factor.
• Divided by the target unit expressed in watt.
• Rounded the result to 12 significant digits.

1 kw = 1000 w

• Both units measure power, so the conversion is a single exact multiplication.

Methodology

1. Express every unit as an exact factor to the watt base.
2. Multiply the input by the source factor and divide by the target factor.
3. Round the result to 12 significant digits so a convert-then-convert-back operation stays within floating-point tolerance.

Usage

1. Enter the value to convert.
2. Choose the source and target units.
3. Read the converted value and the conversion formula.

Kilowatt to watt

{
  "value": 1,
  "from": "kw",

}

Horsepower to kilowatt

{

Limitations

Exact power factors

Every power unit is defined as an exact multiple of the watt, so the conversion is a single multiplication with no approximation beyond floating-point representation.
