About Flow Rate Conversions

Volumetric flow rate measures how much fluid volume passes a point per unit of time. The SI unit is the cubic metre per second (m³/s), but practitioners almost never work at that scale — plumbing uses litres per minute, irrigation uses litres per second or cubic metres per hour, and HVAC balances run on cubic feet per minute (CFM). A key trap in international work is the gallon: the US gallon equals 3.785411784 L while the UK (imperial) gallon equals 4.54609 L, so 1 UK gpm is about 1.201 US gpm. Mixing them silently distorts pump and piping specifications by roughly 20%. A modern efficient shower head flows around 9.5 L/min (2.5 US gpm), while a garden hose at full open delivers 40 to 60 L/min. HVAC engineers translate refrigeration tonnage to airflow: rooftop units often spec 400 CFM per ton. Our converter uses exact SI-to-imperial relationships so that pump head, pipe sizing, and cooling tower duty calculations remain consistent across regions.

How precise are the conversions?

All conversions use exact factors verified against NIST and ISO standards with up to 10 significant figures of precision. Results are calculated using IEEE 754 double-precision arithmetic, which provides approximately 15-17 significant digits. For temperature and other non-linear conversions, exact formulas are used rather than approximations.
