About these units
Nautical Mile (nmi)
The nautical mile is a unit designed specifically for navigation. Its definition—exactly 1,852 meters—originated from the idea that one nautical mile equals one minute of arc along Earth's meridian. This geometric relationship makes nautical miles incredibly convenient for charting and navigation because latitude coordinates are given in degrees, minutes, and seconds. Aviation and maritime industries use nautical miles exclusively for distance, and knots (nautical miles per hour) for speed. Because Earth's shape and size are fundamental to navigational calculations, using nautical miles avoids the complexities that would arise if statute miles or kilometers were used instead. The unit remains globally standardized and universally understood in professional navigation.
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.
