The word "percentage" is often a [[misnomer]] in the context of sports statistics, when the referenced number is expressed as a decimal proportion, not a percentage: "The [[Phoenix Suns]]' [[Shaquille O'Neal]] led the [[NBA]] with a .609 [[field goal percentage]] (FG%) during the 2008–09 season." (O'Neal made 60.9% of his shots, not 0.609%.) Likewise, the [[winning percentage]] of a team, the fraction of matches that the club has won, is also usually expressed as a decimal proportion; a team that has a .500 winning percentage has won 50% of their matches. The practice is probably related to the similar way that [[batting average (baseball)|batting averages]] are quoted.

As "percent" it is used to describe the [[grade (slope)|grade]] or slope, the steepness of a [[road]] or [[Rail tracks|railway]], formula for which is 100&nbsp;×&nbsp;{{sfrac|rise|run}} which could also be expressed as the [[Tangent (trigonometry)|tangent]] of the angle of inclination times 100. This is the ratio of distances a vehicle would advance vertically and horizontally, respectively, when going up- or downhill, expressed in percent.

Percentage is also used to express composition of a mixture by [[mass percent]] and [[mole percent]].
