Convert Cubic inches per minute to US gallons per hour
Convert Cubic inches per minute (in³/min) to US gallons per hour (gph) instantly and accurately.
Conversion Formula
gph = in³/min × 0.2597402597
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.
About US gallons per hour
The US gallon per hour (gph) equals 3.785411784×10⁻³/3600 ≈ 1.051×10⁻⁶ m³/s, common in oil-burner nozzle ratings, water-softener regeneration, and RV/marine-plumbing specifications. Residential oil-burner nozzles are rated in gph (e.g., 0.75 gph, 1.00 gph); a small boat bilge pump might handle 200-500 gph. 1 US gph ≈ 1.052×10⁻⁶ m³/s ≈ 3.785 L/h.
