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.
Foot/Second (ft/s)
The foot per second is an imperial speed unit used in engineering, ballistics, aviation, and certain sports sciences. It expresses the number of feet traveled per second. Ballistics experts use ft/s to measure bullet velocities and projectile speeds, particularly in countries with strong imperial-unit traditions. Engineers may use ft/s in fluid flow calculations or mechanical system design when working with legacy data. Although ft/s is rarely seen in daily life, it remains relevant in niche disciplines where imperial units dominate, offering a smaller, more precise scale than mph.
