efficiency ratings
How well measured
Efficiency ratings are standardized measures of how well a device, system, or process converts input into useful output.
Appliances carry efficiency ratings to help consumers compare energy consumption: The refrigerator's efficiency rating was among the highest in its class.
Similar ratings apply to HVAC systems, vehicles, and industrial equipment.
In sports, efficiency ratings quantify player performance relative to resources used.
