Can this calculator handle different units for mass and radius?

Yes, the tool accepts multiple unit options for mass and radius, converting them automatically to standard physics units for the calculation.

What if I only know the object's rotation speed in revolutions per minute?

You can input angular velocity in revolutions per minute; the calculator will convert it to radians per second internally before computing the energy.

Does the result account for the object's shape or distribution of mass?

The calculator uses a basic moment of inertia formula; for complex shapes, you may need to adjust the moment of inertia value manually or use a more specialized tool.

Is the output energy value in standard SI units?

The default output is in joules, but the tool also provides results in other units like foot-pounds if preferred.
