About these units
Yard/Minute (yd/min)
A yard per minute is used in sports coaching, physical training, and some industrial processes. Coaches may track a swimmer's or runner's speed informally using yards per minute, especially in regions where yard-based pools or tracks still exist. Certain fabric and material-feed systems also use yd/min to specify production speed, as textiles and printing industries historically measured length in yards. The unit bridges athletic training and industrial applications in imperial-unit contexts.
Millimeter/Hour (mm/h)
A millimeter per hour is extraordinarily slow, used in geology, meteorology, and materials science to measure phenomena like soil creep, tectonic plate micro-motion, or extremely light precipitation (drizzle). In manufacturing, mm/h may describe slow deposition rates in thin-film fabrication or high-precision milling processes. Despite seeming negligible, speeds measured in mm/h can accumulate into significant changes over weeks, months, or years—making them essential for long-term studies.
