Convert Cubic yards per hour to Litres per second
Convert Cubic yards per hour (yd³/h) to Litres per second (L/s) instantly and accurately.
Conversion Formula
L/s = yd³/h × 0.2123763494
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 Litres per second
The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.
