Common Flow Rate Conversions
💡 Quick Reference: This calculator supports 40 different flow rate units including metric volumetric (m³/h, L/s), Imperial/US volumetric (gpm, CFM, CFS), oil industry units (bbl/day), and mass flow rates (kg/h, lb/h). All conversions are performed instantly as you type. Note: Mass flow rate conversions assume water density (1000 kg/m³) for volumetric-to-mass conversions.
