Unit choice and order
Quantities are typically expressed using an appropriate "primary unit", displayed first, followed, when appropriate, by a conversion in parentheses e.g. 200 km. For details on when and how to provide a conversion, see the section.

In most articles, the primary units chosen will be SI units, non-SI units officially accepted for use with the SI, or such other units as are conventional in reliable-source discussions of the article topic (such as revolutions per minute (rpm) for rotational speed, hands for heights of horses, etc.).nds for heights of horses, etc.).

Where an non-scientific article has strong national ties to a given country, the primary units are based on the units most commonly used in that country. In particular:
 * In the United States, the primary units are normally US customary (pounds, miles, feet, inches, etc.)
 * In the United Kingdom, the primary units for most quantities are metric or other internationally used units, except that:
 * UK engineering-related articles, including those on bridges and tunnels, generally use the system of units in which the subject project was drawn up (but road distances are given in imperial units, with a metric conversion – see next bullet);
 * the primary units for distance/ length, speed and fuel consumption are miles, miles per hour, and miles per imperial gallon (except for short distances or lengths, where miles are too large for practical use);
 * the primary units for personal height and weight are feet /inches and stones/ pounds;
 * imperial pints are used for quantities of draught beer/ cider and bottled milk;
 * In most other countries, the primary units are normally SI units, non-SI units officially accepted for use with the SI (metres, kilograms etc.).
