Unit converters for fluid and chemical quantities — volumetric flow rate (m³/s, L/min, GPM), density (kg/m³, g/cm³, lb/ft³), dynamic viscosity (Pa·s, cP) and concentration. Essential for chemical, process and hydraulic engineers.
Type a volumetric flow rate in m³/h, L/min, US GPM or CFM and the other three refresh immediately. These four units cover the vast majority of pump, HVAC, pipeline and industrial-cooling applications worldwide, making cross-regional specification comparison fast and error-free.
Enter a gas flow rate and convert between Nm³/h (0 °C, 101.325 kPa), Sm³/h (15 °C, 101.325 kPa) and SCFM (60 °F, 14.696 psia). Provide the actual temperature and pressure to apply the ideal-gas-law correction and obtain accurate standard-condition equivalents.
Enter density in any of the four units and the rest update instantly. Covers the SI standard kg/m³, the materials-science favourite g/cm³ (= g/mL), the US engineering lb/ft³ and the drilling industry ppg (pounds per gallon). Useful for fluid mechanics, buoyancy calculations and oilfield operations.
Enter dynamic (absolute) viscosity in Pa·s or cP, or kinematic viscosity in m²/s or mm²/s (cSt), and the paired unit updates immediately. Dynamic and kinematic viscosity are linked by fluid density (ν = μ/ρ); the two sub-calculators operate independently for maximum flexibility.
Input a vacuum leak rate in Pa·m³/s, mbar·L/s or atm·cc/s and the other two appear instantly. These three units span the full range of leak-testing standards: Pa·m³/s is the SI preferred unit; mbar·L/s is dominant in European vacuum technology; atm·cc/s is common in US military and aerospace MIL-STD leak specifications.
Input a concentration in mol/L, g/L, ppm or ppb and the remaining values update. Provide the molar mass (g/mol) of your solute to enable the mol/L ↔ g/L interconversion. Widely used in chemistry labs, environmental monitoring and pharmaceutical QC.
