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.
Kilometer/Hour (km/h)
The kilometer per hour is a widely used everyday speed unit, especially in transportation. Most countries use km/h for automobile speed limits, train speeds, and vehicle specifications because it aligns naturally with metric distances. Although less mathematically convenient than m/s, km/h provides a human-friendly scale: speeds of 30–120 km/h correspond well to familiar travel activities. Converting between the two units is straightforward (1 m/s = 3.6 km/h), allowing scientists to work in m/s while communicating results in km/h. The use of km/h reflects society's need for intuitive, coarse-grained measurements while maintaining compatibility with scientific standards. Its ubiquity makes it one of the world's most recognized speed measures.
