Convert Cubic inches per second to Cubic metres per second
Convert Cubic inches per second (in³/s) to Cubic metres per second (m³/s) instantly and accurately.
Conversion Formula
m³/s = in³/s × 1.638706400e-5
About Cubic inches per second
The cubic inch per second (in³/s) equals 1.6387064×10⁻⁵ m³/s, used in US automotive engineering for engine displacement sweep rate, fuel-injector calibration, and hydraulic actuator speed specifications. An engine injector delivering 15 in³/s of fuel corresponds to roughly 15.5 mL/s; hydraulic jacks in US equipment are rated in in³/s at operating pressure. 1 in³/s ≈ 1.639×10⁻⁵ m³/s = 0.016387 L/s.
About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/s.
