Residential central air systems are usually from 1 to 5 tons (3.5 to 18 kW) in capacity. For residential homes, some countries set minimum requirements for energy efficiency. In the United States, the efficiency of air conditioners is often (but not always) rated by the seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner. The SEER rating is the BTU of cooling output

The scale "represents a quantum leap in the precision and accuracy of air-cleaner ratings" and allows for improved health, reduced cost and energy efficiency in heating, ventilation and air conditioning (HVAC) design. For example, a HEPA filter is often impractical in central HVAC systems due to the large pressure drop the dense filter material causes.

It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne station. It is a more accurate version of the VOR/DME system that provides bearing and range information for civil aviation. The DME portion of the TACAN system is available for civil use; at VORTAC facilities where a VOR is combined with a TACAN, civil aircraft can receive VOR/DME readings. Aircraft equipped with TACAN avionics can use this system for

Many countries have their own television rating system and countries' rating processes vary by local priorities. Programs are rated by the organization that manages the system, the broadcaster, or the content producers. A rating is usually set for each individual episode of a television series. The rating can change per episode, network, rerun, and country. As such, program ratings are usually not meaningful unless when and where the rating is used is mentioned. A

The Elo rating system has also been used in biology for assessing male dominance hierarchies, and in automation and computer vision for fabric inspection.

The Glicko-2 rating system improves upon the Glicko rating system and further introduces the "rating volatility" σ.

In 2001, Marvel Comics withdrew from the Comics Code Authority and established its own rating system for its publications. This was precipitated by the CCA refusing approval of the seal due to the strong depiction of violence in "X-Force #116", a comic written by Peter Milligan and drawn by Mike Allred. As well, by withdrawing from the CCA, this is seen as a move by editor-in-chief Joe Quesada to lure more high-profile creators to

It was used by the West German Chess Federation from 1948 until 1992 when it was replaced by an Elo-based system, Deutsche Wertungszahl. It influenced some other rating systems. This is a simple system where players' new ratings are the average rating of their competition minus one point for each percentage point above 50
