Use cases

  • Convert wind speed measurements from ft/s sensors to mph for weather reports.
  • Translate athletic sprint speeds (e.g., 100 m dash) recorded in ft/s into mph.
  • Check projectile or vehicle velocities captured by radar guns that output ft/s.
  • Convert fluid flow velocities from engineering calculations to mph for reporting.
  • Cross-check speed limits and regulations that mix ft/s and mph units.
