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). [1]
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.
What Is a Poise?
A poise is a unit of dynamic viscosity equal to 1/10 of a pascal second (0.1 Pa·s). CGS dynamic viscosity unit equal to 0.1 Pa·s. [2]
The poise is classified as a metric and SI-compatible unit of dynamic viscosity. Poise can be abbreviated as P; for example, 1 poise can be written as 1 P.
When working with poise (P) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, poise (P) are widely used across standard dynamic viscosity applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting dynamic viscosity between pound-force seconds per sq. foot (lbf·s/ft²) and poise (P), keep full floating-point precision (1 lbf·s/ft² = 478.8025898 P; 1 P = 0.0020885 lbf·s/ft²) during intermediate calculations and round only the final poise figure to match your instrument tolerance.
