Pound-force Second per Square Foot
lbf·s/ft²
Definition
The pound-force second per square foot is an imperial unit of dynamic viscosity, representing the resistance of a fluid to flow when a force of one pound-force per square foot is applied.
History/Origin
This unit originates from the imperial system of measurements, where force is measured in pounds-force and area in square feet. It was commonly used in engineering applications in the United States and other countries using imperial units.
Current Use
Still used in some engineering contexts, particularly in the United States and other countries that use imperial units. It provides a practical measure for engineers working with force-based calculations in imperial units.

Newton Second per Square Meter
N·s/m²
Definition
The newton second per square meter is equivalent to the pascal second, representing the dynamic viscosity of a fluid when a force of one newton per square meter produces a velocity gradient of one meter per second per meter.
History/Origin
This unit is directly derived from the fundamental SI units of force (newton) and area (square meter). It provides an alternative expression for the pascal second using base SI units.
Current Use
Used in scientific and engineering contexts where it is more convenient to express viscosity in terms of force and area rather than pressure. It is mathematically equivalent to the pascal second.
