UnitConversion.onlineDefinition:
Power density is the amount of power (energy per unit time) contained in a given system or region of space per unit volume or mass. It is measured in watts per cubic meter (W/m³) or watts per kilogram (W/kg) and is essential in applications like fuel cells, batteries, and electric motors.
Example Conversions:
- 1 kilowatt per cubic meter (kW/m³) = 1000 watts per cubic meter (W/m³)
- 1 watt per kilogram (W/kg) = 1 W/kg
- 1 megawatt per liter (MW/L) = 1,000,000 watts per liter (W/L)
