Flow Rate Calculator

Calculate flow rate, cross-sectional area, or velocity using the continuity equation: Q = A × v. Features area units (m², cm², mm², ft², in²), velocity units (m/s, cm/s, ft/s, km/h, mph), and flow rate units (m³/s, L/s, L/min, gal/s, gal/min). Perfect for fluid mechanics and engineering students.
