Kilogram-force Second per Square Meter (kgf·s/m²)

Definition: A gravitational metric unit of dynamic viscosity built from the kilogram-force (the weight of one kilogram under standard gravity) rather than the newton.

History: Rooted in the older 'technical' or gravitational metric system used in European engineering before SI's newton-based units fully displaced force units defined by weight.

Current use: Still encountered in older European mechanical and hydraulic engineering literature and legacy equipment specifications.

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.

From Unit
The unit your input value is currently measured in — a viscometer's centipoise reading, or an engineering spec's Pa·s.
To Unit
The unit you want the result converted into. Use the swap button to flip From and To instantly.

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 Kilogram-force Second per Square Meter → Newton Second per Square Meter: multiply by 9.80665. For example, 1 kgf·s/m² × 9.80665 = 9.80665 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 kgf·s/m² equals 9.80665 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 Kilogram-force Second per Square Meter?

1 Kilogram-force Second per Square Meter (kgf·s/m²) equals exactly 9.80665 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.
