About these units
Walking Speed (walk)
The average human walking speed is about 1.2–1.4 m/s (4–5 km/h), though this varies with fitness, terrain, age, and purpose. Walking is an energy-efficient mode of locomotion optimized through millions of years of evolution. Humans unconsciously adjust stride frequency, step length, and posture to maintain stability and minimize metabolic cost. Urban planning, pedestrian-safety engineering, and architecture all use walking-speed estimates to design sidewalks, crosswalk timing, and public transportation access. Walking speed is not merely a physical measure—it reflects physiology, psychology, and cultural context.
Speed of Sound in Pure Water (vₕ₂ₒ)
The speed of sound in pure water is approximately 1,480 m/s at room temperature, though it varies with temperature and pressure. Sound travels faster in water than in air because water molecules are more tightly packed, allowing vibrations to propagate more efficiently. This speed is critical for sonar systems, underwater communication, acoustic research, and marine biology. Whales, dolphins, and submarines all rely on sound propagation through water, where visibility is extremely limited. Understanding vₕ₂ₒ allows accurate modeling of ocean acoustics, ranging from climate studies to naval operations.
