About these units
Yard/Second (yd/s)
A yard per second is a moderately fast speed, equal to 3 ft/s or 0.9144 m/s, used in some athletic contexts—particularly American football or sprinting analysis. It provides an intuitive measure for sports where yard-based distances dominate. Because the unit aligns with common field dimensions, it simplifies performance evaluation in training and gameplay. The yard per second reflects the enduring influence of imperial measurements in American athletics.
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.
