About these units
Hectometer (hm)
A hectometer is equal to 100 meters, and though rarely used colloquially, it remains relevant in specific scientific and geographic applications. In meteorology, cloud ceiling heights and visibility distances are sometimes expressed in hectometers. In agriculture, field lengths and irrigation layouts may also be measured in hectometers, offering a compromise between the small meter unit and the more expansive kilometer. Because it aligns nicely with the metric system's decimal structure, the hectometer appears in statistical summaries or technical documents that benefit from uniform numerical scaling. Its relative rarity in day-to-day speech stems from the fact that kilometers are generally more intuitive when discussing larger distances, but in some countries, especially in Europe, hectometers still appear on roadside markers.
Fathom (US Survey) (fath (US))
The US Survey Fathom is defined as 6 US Survey Feet (~1.8288 meters), identical in proportion to the traditional fathom but scaled to the US Survey Foot. Maritime surveys, early river navigation, and hydrographic measurements relied on this unit for determining depths and plotting charts. In terrestrial applications, the fathom occasionally served as a practical measure for large structures or obstacles. Although less relevant in contemporary usage, understanding the US survey fathom is crucial for interpreting historical navigation data, nautical charts, and engineering projects using older measurement systems.
