Units explained
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.
Span
A span is an Imperial unit of length equal to 9 inches (228.6 mm). Historically, it represented the distance from the tip of an extended thumb to the tip of an extended little finger.
The span derives from this natural body-measurement and was standardised at 9 inches in English customary practice.
Spans are rare in modern commerce but appear in historical English literature, biblical translation studies, and reproduction crafts. Some construction and gardening still use 'span' informally.
Ancient body-measure origin; standardised in English customary practice at 9 inches; became exact via the 1959 International Yard and Pound Agreement.
