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.
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.
