Units explained
Inch
An inch is an Imperial and US customary unit of length defined since 1959 as exactly 25.4 millimeters (0.0254 meters). It is still the standard small unit of length in the United States, the United Kingdom (informally), and a few other countries.
The inch derives from the Roman uncia (one-twelfth of a foot) and survived through Anglo-Saxon and medieval English measurement systems. Various definitions persisted regionally until the 1959 International Yard and Pound Agreement standardized the inch globally as exactly 25.4 mm.
Inches are used in the US and UK for body height, screen sizes (TVs, monitors, phones), tire sizes, plumbing, lumber, paper sizes (US Letter is 8.5 × 11 in), and most consumer product specifications in the United States.
Anglo-Saxon origin (predating 1066); standardized to 25.4 mm exactly by the International Yard and Pound Agreement of 1959, signed by the US, UK, Canada, Australia, New Zealand, and South Africa.
Kiloyard
A kiloyard is an Imperial unit of length equal to 1,000 yards (914.4 m). It is rarely used in everyday measurement but appears in some technical and military contexts.
The kiloyard combines the metric-style prefix kilo- (Greek chilioi, thousand) with the yard. Standardised via the 1959 International Yard and Pound Agreement.
Kiloyards appear in some artillery and military range specifications, sport-shooting long-range competitions, and certain industrial applications. Less common than the mile for most distances.
Modern usage; standardised through the 1959 International Yard and Pound Agreement.
