Percenten

Percenten is a term used to refer to percentages, which express a portion per hundred. In this article, percenten is treated as a plural form for percent values in some contexts, though the standard English plural is percentages. Percenten are unitless numbers used to describe parts of a whole, commonly written with the symbol % or the word percent.

Notation and conversion: 1 percent equals 0.01. To convert a percenten to a decimal, divide by 100. To convert a decimal to a percent, multiply by 100 and attach the % sign. Example: 25% equals 0.25; 0.75 equals 75%.

Calculation and interpretation: Percenten describe a proportion relative to a base of 100 units. When expressing changes, it is important to distinguish between a percentage change (relative change to a base value) and a change in percentage points (an absolute difference of the percenten values). For instance, an increase from 20% to 40% is a 100% relative increase but a 20 percentage-point change.

Applications and pitfalls: Percenten are widely used in statistics, finance, economics, and demographics to summarize data, compare groups, and report results. They are sensitive to the choice of base value; stating the base clearly avoids misinterpretation. Rounding and aggregation can also affect perceived results, especially with small bases or very large values.

Relation to related terms: A percentile is a different concept, describing the value below which a given percentage of observations fall in a distribution. A percenten is a share of a whole, not a position in a ranked distribution. See also: percentage point, decimal, fraction, percentile.
