unitadjusted

Unitadjusted is a descriptive term used across disciplines to indicate that a quantity has been scaled to a common unit or expressed on a per-unit basis to enable direct comparison. It is not a single standardized concept, but a practice of normalizing measurements by unit size or by a reference unit.

In practice, unit adjustment involves applying a conversion so that different quantities share a common unit. The general rule is adjusted_value = raw_value × (reference_unit / original_unit). A common example is calculating price per unit, such as price per liter. If a bottle contains 0.75 liters and costs $3, the unit-adjusted price is $3 ÷ 0.75 L = $4 per liter. Similar adjustments can be made for weight, length, or other measures. In currency contexts, prices can be expressed per unit of a standard size or converted to a common currency to facilitate comparison, though currency conversion introduces exchange-rate considerations rather than a pure unit adjustment.

Contexts and uses. Unit adjustment appears in economics, retail analytics, metrology, and statistics as a method for fair comparison across items that differ in size, volume, or denomination. It supports decision-making, pricing analysis, and data aggregation by removing size effects that would otherwise distort comparisons. However, unit adjustment can distort interpretation if the chosen unit is not meaningful for the comparison or if nonlinear relationships exist between size and value.
