About these units
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.
Millimeter/Second (mm/s)
A millimeter per second is a useful speed in robotics, precision machining, biomechanics, and controlled engineering systems. Robotic arms performing delicate manipulation, small servo motors, and scanning instruments often operate in the mm/s speed range. In seismology, mm/s measures the vibration velocities of the ground during micro tremors, making it essential in structural engineering and earthquake monitoring. It reflects the world of fine-scale, controlled motion—beyond what the human eye typically detects.
