Different cities use different words and units. Add what you know so the little calculator can get better.
This is not asking for anything personal. It can be old, from a city you visited once, or from where you live now: what it is called, what a bag typically weighs, etc.
Fill out one form per city. Send it in, then start a new one for the next city.
City is the one thing we really need. Do not include a corner, address, dealer, phone number, or anything that points to a person.
