What Is a Pound per Foot-Second?
A pound per foot-second is a unit of dynamic viscosity equal to 1.4881639 pascal seconds (Pa·s), the base unit for dynamic viscosity. Imperial dynamic viscosity unit (≈ 1.4882 Pa·s). [1]
The pound per foot-second is classified as a US customary unit of dynamic viscosity. Pounds per Foot-Second can be abbreviated as lb/(ft·s); for example, 1 pound per foot-second can be written as 1 lb/(ft·s).
When working with pounds per foot-second (lb/(ft·s)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pounds per foot-second (lb/(ft·s)) are widely used across standard dynamic viscosity applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Pound-force Second per Sq. Foot?
A pound-force second per sq. foot is a unit of dynamic viscosity equal to 47.880259 pascal seconds (Pa·s), the base unit for dynamic viscosity. Gravitational US viscosity unit (≈ 47.88 Pa·s). [2]
The pound-force second per sq. foot is classified as a US customary unit of dynamic viscosity. Pound-force Seconds per Sq. Foot can be abbreviated as lbf·s/ft²; for example, 1 pound-force second per sq. foot can be written as 1 lbf·s/ft².
When working with pound-force seconds per sq. foot (lbf·s/ft²) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-force seconds per sq. foot (lbf·s/ft²) are widely used across standard dynamic viscosity applications within US customary workflows, engineering documentation, and technical data sheets.
When converting dynamic viscosity between pounds per foot-second (lb/(ft·s)) and pound-force seconds per sq. foot (lbf·s/ft²), keep full floating-point precision (1 lb/(ft·s) = 0.031081 lbf·s/ft²; 1 lbf·s/ft² = 32.1740486 lb/(ft·s)) during intermediate calculations and round only the final pound-force second per sq. foot figure to match your instrument tolerance.
