What two variables does mass depend on?

Mass itself is a fundamental property of an object and does not depend on variables in the way that weight or volume does. Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg), grams (g), or other units of mass. It does not change based on the object’s location, state of motion, or other variables such as temperature or pressure (except in cases with extreme relativistic conditions or significant chemical changes where mass can be converted to energy and vice versa according to Einstein's equation E=mc^2).

The confusion might arise with the concept of weight, which depends on two variables: the mass of an object and the acceleration due to gravity. Weight is a force and is calculated as the mass of an object multiplied by the gravitational acceleration (w = m * g), where 'w' is the weight, 'm' is the mass, and 'g' is the acceleration due to gravity.
