About these units
Foot (ft)
A foot, equal to 12 inches, has been used for thousands of years and likely originated from the length of a human foot. Though early definitions varied, the modern standard foot—established internationally in 1959—provides a stable and consistent reference. The foot remains the foundation of architectural and construction measurements in the United States, influencing everything from lumber dimensions to ceiling heights and room layouts. Because the foot is intuitively relatable to human scale, people often estimate heights, furniture sizes, and walking distances in feet. In aviation, altitude is universally measured in feet worldwide, even in countries that otherwise use metric units—an unusual but deeply embedded global convention. The foot's persistence shows how cultural inertia can remain strong even when a unit predates modern scientific measurement.
Dekameter (dam)
A dekameter (sometimes spelled "decameter"), equal to ten meters, is another unit in the metric system that is infrequently used in everyday life. Its primary applications arise in surveying, topographic mapping, and environmental science. When measuring the heights of waves, depth increments in lakes, or widths of natural features like river channels, the dekameter provides a convenient scale—large enough to avoid cumbersome numbers yet small enough to maintain meaningful detail. While modern GPS and digital mapping tools often use meters directly, the dekameter persists in specialty fields that value standardized interval measurements. For example, contour intervals on geographic maps may be expressed in dekameters for uniformity. The unit's relative obscurity reflects the public's preference for units with intuitive relevance (like meters and kilometers), but its presence is nonetheless important in systematic metric progression.
