Our concern here

This web page allows you to convert the different moment of inertia units and answers the following questions in particular: What is moment of inertia and what physical quantity does it represent? What are the centimeter-gram-second (CGS) system and the International System of Units (SI), and what is their unit of measurement for moment of inertia? What are some examples of reference or record values for moment of inertia, and what are their units of measurement? What is the formula used to convert between CGS units and SI units for moment of inertia, and can you provide an example? Why is moment of inertia a useful tool for understanding the effects of rotation on an object, and how is it related to an object's shape and size?

Introduction to Moment of Inertia

Moment of inertia is a term used to define an object’s resistance to change its rotation speed or its shape. Moment of inertia (also known as second moment of area, rotational inertia, area moment of inertia, integral of inertia and polar moment of inertia, among other terms) is a physical quantity used to represent the torque of a body or a system of particles. It is a measurement related to the mass distribution of the body and its shape and has proven to be a useful tool for understanding the effects of rotation on an object. In general, the shape and size of an object will determine the moment of inertia it has.

History of Different Units

Since the earliest days, physicists and engineers have been looking for ways to measure this angular motion and its effect on a body. In the late 18th and early 19th centuries, a number of different systems were developed to measure and quantify rotational motion. However, the conventional scales and units of measurement used to describe angular motion were inadequate for these purposes. This is why various authors proposed different systems of measurement specifically designed for quantifying the effects of rotational motion.

The most important of these systems is the centimeter-gram-second (CGS) system, which is still in use today. In the CGS system, the unit of moment of inertia is the dyne-centimeter squared (dyne cm2). This unit of measurement is still used in many applications, including the study of mechanics and engineering. The CGS system also defines two other related units, the gram-centimeter squared (gm-cm2) and the gram-meter squared (gm-m2).

The second most important system for measuring angular motion is the International System of Units (SI). In the SI system, the unit of moment of inertia is the kilogram-metre squared (kg·m2). This unit of measurement is widely used in many applications, including the study of dynamics, aerodynamics and aerospace engineering.

Reference Values of Moment of Inertia

Conversion between Different Units

Since the two most common systems of measurement for Moment of Inertia are the centimeter-gram-second system (CGS) and the International System of Units (SI), a conversion formula must be used to accurately convert between the two systems. To convert from a CGS unit to an SI unit, the following formula can be used: SI unit = CGS unit x 0.01

For example, to convert a value of 0.001 g·cm2 to an SI unit, the following calculation can be used: 0.001 g·cm2 x 0.01 = 0.00001 kg·m2.

Summary

Moment of Inertia is a measurement of an object’s resistance to change its rotation speed or its shape. It is measured in different units, such as dyne-centimeter squared, gram-centimeter squared, gram-meter squared, kilogram-meter squared, newton-meter squared, slug-foot squared, slug-inch squared, ounce-inch squared, pound-foot squared and pound-inch squared. Conversion between the two most common systems of measurement for Moment of Inertia, the centimeter-gram-second system (CGS) and the International System of Units (SI) can be done using the formula SI unit = CGS unit x 0.01.
