The barn (b) is a unit of area used in nuclear physics equal to one hundred femtometres squared (100 fm 2 = 10 −28 m 2). The are (a) is a unit of area equal to 100 m 2. The decare (daa) is a unit of area equal to 1000 m 2. The hectare (ha) is a unit of area equal to 10 000 m 2 (0.01 km 2).

A unit of measurement that applies to money is called a unit of account in economics and unit of measure in accounting. [5] This is normally a currency issued by a country or a fraction thereof; for instance, the US dollar and US cent (1 ⁄ 100 of a dollar), or the euro and euro cent.

A weight (also known as a mass) is an object, normally with high density, whose chief task is to have mass and exert weight (through gravity). It is used for different purposes, such as in: It is used for different purposes, such as in:
Balance scale set, with weights Scales used to measure the weight of fruit in a supermarket Weighing scale in use in Tokyo Digital kitchen scale, a strain gauge scale Weighing scale for a baby includes a ruler for height measurement. A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight ...
In 1965, the UK began an official programme of metrication, and as of 2025, in the United Kingdom the metric is the official measurement system for all regulated trading by weight or measure purposes, however imperial pint remains the sole legal unit for milk in returnable bottles and for draught beer and cider in British pubs.
Nonetheless, the residual and irreducible instability of a physical IPK undermined the reliability of the entire metric system to precision measurement from small (atomic) to large (astrophysical) scales. [39] By avoiding the use of an artefact to define units, all issues with the loss, damage, and change of the artefact are avoided. [1]: 125
