    Default What's a millimeter?

    I recently took advantage of what seemed to be a good deal from a US eBay storefront for some 200x120x75 mm project boxes--a good size for some of my stuff. What I (promptly) received were boxes that measure perhaps 75x40x25 mm. When contacted, the seller admits that he doesn't have any of the item advertised for sale and that he found the measurements "confusing".

    I blame schools in the US for ignoring the metric system.

    Huh? Did he just search by image for stuff by the same manufacturer, and picked one that sort of looked right, or what?

    That's not really ignorance of measurement system, that's straight up laziness and not wanting to put in the effort to sell the item. Because while using metric measurements, when you grew up with imperial ones, can be a bit confusing, it is not rocket science, a 30 second google search would have helped them get it right, or at least much closer than it really was.

    Did they refund you at least?

    Refund is in the works. Now I've got to find a seller who has the real thing at a decent price...

    It looks like he measured, using a metric ruler, thinking it was inches and not being able
    to multiply by 2.54, multiplied by 3 ( close enough? ).

    No, the dimensions are listed in mm in the advertisement (no imperial units at all) and the most charitable explanation is that he slipped a decimal, although that's probably not what actually happened.

    Every tape measure and ruler has English and metric on it since forever.

    The sizes the seller sent were not even close.

    I went to school a long time ago and the metric system was never ignored. Metric should be pretty easy to learn and understand since it is based on factors of 10. US systems are a mess that remind me of grammar rules made up as you go along.

    Bad seller on eBay == bad schools in the US? Seems like quite a stretch.

    You get what you pay for. Why I use electronic distributors for project parts where I have a known manufacturer and their part number for repeat sourcing. Something rarely found or accurate on eBay.

    Bad US *retailer* on eBay. Of course the reason could be sloppiness or laziness, but seeing as how the repercussions from that are financial, it doesn't make a lot of business sense. Likely the seller had no idea of what he was doing.
