You could tell me what you do want to do, and I will search the available services for a way to achieve that.

How do I know my pant size?
user
My sensors are configured to detect a person’s height and weight in order to estimate their basic body mass, such that the conversion to pant size can be done by reference to a table of garment conversion.  Do you wish to know your body mass?
assistant
No, I don't.
user
Let me know if you do, though.
assistant
So what can I do?
