What is the ratio of inertial mass to gravitational mass.

same thing.

The ratio of inertial mass to gravitational mass is commonly denoted as "Equivalence Principle" in physics. According to this principle, the inertial mass and the gravitational mass of an object are equivalent, meaning that they are proportional to each other.

To find the ratio of inertial mass to gravitational mass, one can perform the following steps:

1. Measure the inertial mass: To determine the inertial mass of an object, you can use a device called an "inertial balance." This device measures the resistance an object exhibits when subjected to an applied force. By dividing the applied force by the acceleration produced, you can obtain the inertial mass.

2. Measure the gravitational mass: To determine the gravitational mass of an object, you can use a balance scale. Place the object on one side of the scale and add calibrated weights on the other side until the scale is balanced. The sum of the weights will represent the gravitational mass of the object.

3. Calculate the ratio: Once you have obtained the measurements for both the inertial mass and gravitational mass, divide the value of the inertial mass by the value of the gravitational mass. The result will give you the ratio of inertial mass to gravitational mass.

It is important to note that extensive experimental evidence has found that the ratio of inertial mass to gravitational mass is indeed very close to unity, confirming the Equivalence Principle in physics.
