Pound per Foot per Hour (lb/(ft·h))

Definition: A small-scale US customary viscosity unit that swaps the second for the hour, useful for low-viscosity fluids measured over longer process timescales.

History: Derived from pound per foot per second by substituting the hour for the second, matching the hourly timescales common in continuous industrial process monitoring.

Current use: Occasionally used in US chemical and process engineering contexts where flow rates and process data are already tracked on an hourly basis.

Newton Second per Square Meter (N·s/m²)

Definition: Numerically and dimensionally identical to the pascal second — a newton second per square meter is simply the pascal second written out in its base SI force, time, and area components.

History: Predates the pascal's adoption as a named SI unit; early SI fluid-mechanics texts expressed viscosity this way before the pascal second became the preferred shorthand.

Current use: Still appears in physics textbooks and derivations that build viscosity up from Newton's law of viscosity rather than starting from the named pascal unit.

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 Pound per Foot per Hour → Newton Second per Square Meter: multiply by 0.0004133789. For example, 1 lb/(ft·h) × 0.0004133789 = 0.0004133789 N·s/m².

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 lb/(ft·h) equals 0.0004133789 N·s/m². 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 Newton Seconds per Square Meter are in 1 Pound per Foot per Hour?

1 Pound per Foot per Hour (lb/(ft·h)) equals exactly 0.0004133789 Newton Seconds per Square Meter (N·s/m²).

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.
