Convert Cubic feet per second to Cubic inches per minute
Convert Cubic feet per second (ft³/s) to Cubic inches per minute (in³/min) instantly and accurately.
Conversion Formula
in³/min = ft³/s × 103680
About Cubic feet per second
The cubic foot per second (ft³/s or cfs) equals 0.028316846592 m³/s, the primary unit for measuring river discharge and open-channel flow in the United States. The US Geological Survey publishes all streamflow data in cfs; irrigation water rights, flood-control gates, and dam spillway capacities are specified in cfs. The Colorado River at full natural flow is ≈22 000 cfs. 1 cfs = 0.028316846592 m³/s ≈ 28.317 L/s ≈ 448.8 US gpm.
About Cubic inches per minute
The cubic inch per minute (in³/min) equals 1.6387064×10⁻⁵/60 ≈ 2.731×10⁻⁷ m³/s, common in US pneumatic and hydraulic circuit design. Air-tool consumption is rated in SCIM (standard cubic inches per minute); small hydraulic cylinders advancing at 10 in/min with 1 in² bore consume 10 in³/min: exactly 0.163 mL/s. 1 in³/min ≈ 2.731×10⁻⁷ m³/s.
