Conversion Formula
qt/s = yd³/h × 0.2244155844
About Cubic yards per hour
The cubic yard per hour (yd³/h) equals 0.764554857984/3600 ≈ 2.124×10⁻⁴ m³/s, the standard unit for concrete pump output, earthwork compaction flow, and US dredging production rate reporting. A concrete pump truck delivers 30-80 yd³/h on a high-rise pour; a cutter-suction dredger handles 100-500 yd³/h in harbour maintenance. 1 yd³/h ≈ 2.124×10⁻⁴ m³/s.
About US quarts per second
The US quart per second (qt/s) equals 3.785411784×10⁻³/4 ≈ 9.464×10⁻⁴ m³/s, used in US industrial filling lines handling quart-size containers (motor oil, paint, sauce). A high-speed filling machine loading 1 qt bottles at 4 per second processes 4 qt/s per nozzle. 1 US qt/s ≈ 9.464×10⁻⁴ m³/s = 0.9464 L/s.
