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.
Speed of Light (c)
The speed of light in a vacuum, denoted c, is exactly 299,792,458 m/s, one of the most fundamental constants of physics. Light speed defines the structure of spacetime, the upper limit for classical information transfer, and the basis for relativity. Time dilation, length contraction, and mass-energy equivalence (E = mc²) all arise from the invariance of c. In astronomy, the speed of light is used to define light-years, measure cosmic distances, and synchronize observations across telescopes. In communication technology, optical networks rely on light-speed propagation through fiber, albeit slightly slower than in vacuum. c is not just a speed—it is a cornerstone of the physical universe.
