Definition: W/kg


(Watts per KiloGram) A power-to-weight ratio. W/kg is used to measure the power generated by an engine divided by its mass. For example, a 300 horsepower engine weighing 800 pounds is converted to 224 kilowatts and 363 kilograms, and the W/kg is 0.61. The measurement of electromagnetic waves absorbed into the body is given in W/kg (see SAR).
