Power Converter

This online power converter recalculates values across nine standard mechanical, electrical, and thermal power units. You can convert between watts, kilowatts, megawatts, gigawatts, horsepower, BTU per hour, calories per second, kilocalories per hour, and foot-pounds per second. The tool takes a numeric value, applies the corresponding ratio between your selected source and target units, and displays the converted quantity rounded to ten decimal places. Common tasks include converting appliance wattage to kilowatts for energy calculations, checking mechanical engine output from horsepower to watts, or translating heating ratings from BTU per hour into electrical equivalents. If you leave the value blank, the converter defaults to zero. When you enter an alternate text string that cannot be evaluated as a valid number, the converter treats the value as zero. You can avoid unsupported unit combinations by choosing directly from the provided source and target menus.
