# Viscosity Converter - Convert between Viscosity Units

The Free Online Viscosity Converter helps you convert one measuring unit of viscosity into another measuring unit.

You can convert between newton second per square meter, centipoise, centistoke, square foot per second, poise, stoke, and support many other conversions. Instantly convert one unit to all others.

## What do you mean by viscosity?

The answer is quite simple. The viscosity is the thickness of the fluid.

Let explain this with an example. Suppose you have a cup with a hole, and you pour the honey in it. You will see that the honey will slowly drain out from the cup's hole.

But what if you pour the water into the same cup. The result will be different. The water quickly pours out from the cup's hole.

That happens because of viscosity. Both fluids have different viscosity.

Therefore, viscosity is defined as the measure of fluid's resistance to flow.

In other words, it is the friction within the fluid that resists motion. The honey has more viscosity than water because its molecular structure allows it to create friction and resist motion.

Similarly, syrup has a higher viscosity than water.

The formula to measure the viscosity is

F / A = n (dv / dr)

where

• F / A = force divided by area
• n = constant unit equal to 0.00089 Pa s (Pascal-second)
• (dv / dr) = sheer rate

## Types of viscosity

There are two types of viscosity.

1. Dynamic viscosity or Absolute viscosity measures the shear stress ratio to the shear rate for a fluid.
2. Kinematic viscosity measures the dynamic viscosity divided by density. The unit to measure the kinematic viscosity is stoke (one centimeter squared per second).

People mostly get confused between these two viscosity measures. However, they both are different from each other.

### What is the unit to measure the viscosity?

The viscosity is measured in newton-second per square meter (N·s/m2), expressed as pascal-second (Pa·s) in SI units. The other units to measure viscosity are centipoise, centistoke, square foot per second, poise, stoke, etc.

## Why do we need to calculate the viscosity?

Measuring the viscosity is essential because it helps the manufacturer predict how the material will behave in the real world.

After all, it helps in designing the production and the transportation system. Suppose if the toothpaste does not have the correct viscosity. It will be either too difficult to pump out the paste from the tube or vice-versa.

Before putting the oil into your vehicle, you must have an idea about the oil's viscosity. Because the thickness affects friction, and friction affects the heat.

### Online conversion tool V/S Manual conversion, which one is better?

After the technological revolution, the most significant change that happened is that the machine replaces the human. And we brought the standards in our lives by moving from estimated calculations to proper and accurate calculations.

Even though the machines are built and programmed by humans, therefore, they are preferred over humans because they give you accurate and correct results within no time.

The viscosity is measured in Newton-second per square meter (N·s/m2). However, other measuring units are still used, like centipoise, centistoke, square foot per second, poise, stoke, etc., to measure the viscosity.

Moreover, sometimes, you have to convert one measuring unit of viscosity into another measuring unit. Here the online viscosity unit converter helps you a lot for accurate and precise conversion.

#### How to convert Newton-second per square meter (N·s/m2) to a centipoise (cP) using an online viscosity unit converter tool?

An online viscosity unit converter tool makes the conversion process easy. You can easily convert one measuring unit of the viscosity to another measuring unit within no time.

To do this, follow the below-mentioned steps.

• Open the Online Viscosity Unit Converter Tool.
• Enter the amount 1 in the first column.
• In the second column, "Select from," select Newton-second per square meter (N·s/m2) as a measuring unit from which you want to convert.
• In the third column, "Select to," select centipoise (cP) as a measuring unit in which you want to convert.
• Click on the "convert" button; the result will be 1000 centipoise (cP) within no time.
• Therefore, 1 Newton-second per square meter (N·s/m2) = 1000 centipoise (cP).

Note: You will adopt the same conversion procedure between newton second per square meter, centipoise, centistoke, square foot per second, poise, stoke, poundal second/square foot, poundal force-second/square foot, Rhe, slug/foot-second, and stoke.
