About these units
Cycling Speed (cycle)
Typical cycling speeds vary dramatically by context: Casual cycling (4–7 m/s or 15–25 km/h), Road cyclists (8–12 m/s or 30–45 km/h), Professional racing (12–15 m/s or 45–54 km/h), Sprint track cyclists (peaks of 20 m/s or 72 km/h or more). Cycling is highly efficient due to mechanical advantage and reduced ground friction. Aerodynamics becomes a dominant factor at higher speeds, shaping bicycle frame design, wheel geometry, and rider posture. Cycling speeds inform urban infrastructure (bike lanes, safety regulations), sports training, and commuter planning. As a hybrid of human physiology and mechanical engineering, cycling speed provides insight into how technology amplifies natural human motion.
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.
