Flow Rate Conversion FAQ
How do I convert liters per second to gallons per minute?
Multiply the L/s value by 15.8503 to get GPM. For example, 2 L/s = 31.7 GPM. This conversion is commonly used in HVAC and plumbing applications.
What's the difference between volume flow and mass flow rates?
Volume flow rate measures the volume of fluid passing through a point per unit time (L/s, GPM), while mass flow rate measures the mass of fluid (kg/s, lb/min). Volume flow depends on fluid density.
How accurate are these flow rate conversions?
All conversions use internationally recognized conversion factors and are accurate to multiple decimal places. They're suitable for professional engineering calculations.
Can I use these conversions for gas flow rates?
These conversions work for any fluid, but gas flow rates are often measured at standard conditions (STP or NTP) due to compressibility effects. Always specify conditions for gas flows.
What flow rate units are most common in HVAC?
HVAC systems commonly use CFM (cubic feet per minute) for air flow and GPM (gallons per minute) for water flow. International systems use L/s or m³/h.
