units for inverse kinematics

[SaraBaber]

Hello

I know that the units for angle that IK uses are radains but what are the units for lengths and other parameters ?

If we try to set them in our kinematic parameter and then feed it into IK function its gives error.

saying units not matching. because IK function contains VI inside that we cannot chnage

So what are the default units?

Can please anybody help me regarding that?

There shouldn't be any units used.  Whatever you consider for the units should be the same as whatever you defined for the geometry.  So if your coordinate values are inches, then everythhing is based on inches.  If  you considered your distances to be feet, then your values are all in feet.

Thanks alot! So that means we even donot need to specifiy units of our cordinate system? because its not letting me do that too!

I am right so whatever value I will enter in my cordinate space with respect to units that I have in my mind, I have to follow those units everywhere!?
