Poundal Second per Square Foot (pdl·s/ft²)
Definition: A US customary unit of dynamic viscosity built from the poundal, the absolute (mass-based) unit of force in the foot-pound-second system, rather than the gravitational pound-force.
History: Reflects the foot-pound-second 'absolute' system used in some 19th and early 20th century British and American engineering texts as an alternative to gravitational force units.
Current use: Rare today; occasionally found in older engineering references that used the absolute foot-pound-second system rather than the gravitational pound-force system.
Millipoise (mP)
Definition: One thousandth of a poise — a fine-grained CGS unit sized for very low-viscosity fluids such as gases and light vapors.
History: A natural CGS submultiple used wherever the poise or centipoise scale would still read as an inconveniently small fraction, particularly for gas viscosities.
Current use: Occasionally used in physics and chemistry literature reporting the viscosity of gases and very thin liquids.

How Viscosity - Dynamic Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the pascal second. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Poundal Second per Square Foot → Millipoise: multiply by 14881.639. For example, 1 pdl·s/ft² × 14881.639 = 14881.639 mP.
Dynamic Viscosity vs. Kinematic Viscosity
This page converts DYNAMIC (absolute) viscosity — the pure resistance-to-shear property of a fluid, independent of how heavy that fluid is. The site's separate Viscosity - Kinematic Converter covers a related but different quantity: kinematic viscosity equals dynamic viscosity divided by the fluid's density. Because that division depends on a specific fluid's density at a specific temperature, there is no fixed multiplier that converts a dynamic-viscosity unit directly into a kinematic-viscosity unit the way this page converts between, say, pascal seconds and poise — you need to know the fluid's density first.
Poise and Centipoise
Although the pascal second is the modern SI unit, the CGS-era poise and, especially, the centipoise remain the units most commonly quoted in industry and on viscometer readouts. Water at room temperature (about 20°C) has a dynamic viscosity of almost exactly 1 centipoise, which makes it a convenient mental reference point: a fluid rated at 10 cP is roughly ten times "thicker" than water, one rated at 100,000 cP behaves more like honey or ketchup.
Example
A dynamic viscosity of 1 pdl·s/ft² equals 14881.639 mP. For scale, water at room temperature is about 1 cP (0.001 Pa·s), typical motor oil at operating temperature runs from roughly 50 to 300 cP, and honey can measure anywhere from 2,000 to 10,000 cP depending on temperature and water content.
Frequently Asked Questions
How many Millipoises are in 1 Poundal Second per Square Foot?
1 Poundal Second per Square Foot (pdl·s/ft²) equals exactly 14881.639 Millipoises (mP).
What is dynamic viscosity?
Dynamic (absolute) viscosity is a measure of a fluid's resistance to shear or flow — how much internal friction it has as one layer of fluid slides past another. It's what makes honey pour slower than water, and it's typically measured with a viscometer in units like pascal seconds or centipoise.
How is dynamic viscosity different from kinematic viscosity?
Dynamic viscosity measures pure resistance to shear. Kinematic viscosity is dynamic viscosity divided by the fluid's density, and is used mainly in flow calculations where gravity and inertia matter (e.g. how a fluid drains under its own weight). Converting between the two requires knowing the specific fluid's density, so this page and the site's Viscosity - Kinematic Converter are kept separate.
Why is centipoise still used instead of the SI pascal second?
Centipoise predates the pascal second and happens to land on convenient, easy-to-read numbers for common fluids — water is about 1 cP, light oils are tens of cP, heavy syrups are thousands of cP — so most viscometers, product data sheets, and industry standards continued reporting in cP even after SI officially adopted the pascal second.
How accurate are these conversions?
Every conversion factor used here is the exact, internationally recognized relationship between the underlying force, time, and area units — results are limited only by floating-point display precision, not by rounded conversion constants.
