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.

oh thank you =), so how can I determine the SI units for inertial mass?

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?
