Power Converter
Convert watts, kilowatts, megawatts, horsepower, and BTU per hour. Used for appliance ratings, engine output, renewable energy systems, and electrical load planning.
Formula
target = source × (sourceToBase / targetToBase)
Power is normalized to watts (W). One watt equals one joule per second. Horsepower and BTU/h use standard conversion factors to watts.
Example
- Convert: 1 m × 3.28084= 3.28 ft
Result: 1 meter = 3.28 feet
