What are the standard units for inertial mass and gravitational mass?

    [SOLVED] What are the standard units for inertial mass and gravitational mass?

    1. What are the standard units for inertial mass and gravitational mass? And also apparently gravitational mass can be measured without gravity how can it be done?

    Thank you very much. My teacher said a hint is in the movie A space odysey 2001.

    That would be incorrect. Its not a trick question. What units do you usually use for mass?

    we would use kg, or grams, etc.

    Well the SI unit is kg.

    What units do you use for mass in equations like F=ma?

    oh also kilograms, so that means the inertial mass is in kilograms too?
