Convert Acre-feet per second to Cubic yards per hour
Convert Acre-feet per second (ac-ft/s) to Cubic yards per hour (yd³/h) instantly and accurately.
Conversion Formula
yd³/h = ac-ft/s × 5808000
About Acre-feet per second
The acre-foot per second (ac-ft/s) equals 1233.48183754752 m³/s, an enormous unit representing the flow that would fill a football-field-sized area to 1 ft depth every second. It appears in descriptions of exceptionally large dam-break flood waves and major river-system extreme events. The 1976 Teton Dam collapse peak outflow was estimated at ≈65 000 ft³/s ≈ 1.49 ac-ft/s. 1 ac-ft/s = 1 233.48 m³/s.
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.
