Frequently Asked Questions — Fluids Converters

Question: What fluid units can I convert?

Answer: Fluids Converters cover dynamic viscosity, kinematic viscosity, surface tension, flow rate (mass and volume), concentration (molar and solution), permeability, and more — all the fluid mechanics units used in engineering, chemistry, and physics.

Question: What is dynamic viscosity?

Answer: Dynamic viscosity measures a fluid's resistance to flow under an applied shear stress. It is measured in Pascal-seconds (Pa·s) in SI units, or centipoise (cP) in CGS units. Water at 20°C has a dynamic viscosity of about 1 cP (0.001 Pa·s).

Question: How do I convert gallons per minute to liters per second?

Answer: 1 US gallon per minute (gal/min) = 0.063090 liters per second (L/s). To convert, multiply gal/min by 0.063090. For example, 100 gal/min = 6.309 L/s.

Question: What is kinematic viscosity?

Answer: Kinematic viscosity is dynamic viscosity divided by the fluid's density. It represents how fast a fluid flows under gravity. It is measured in square meters per second (m²/s) in SI units, or centistokes (cSt) in CGS units. 1 cSt = 1 mm²/s.

Question: How do I convert psi to bar?

Answer: 1 psi (pound per square inch) = 0.0689476 bar. To convert psi to bar, multiply by 0.0689476. For example, 100 psi = 6.89476 bar. Conversely, 1 bar = 14.5038 psi.
