I saw that too. Interested to see the use of metric system (75 km long roll, 165 cm wide inner tube). I presume that the narrator is just reading a script which is based on the actual units the toilet paper company uses. I used to travel to Europe often and always been the butt of the metric system jokes (I am American) but I think people do not understand is that metric system is used more widely than they think in the US. It is the official system of the USA (Pub. L. 94-168, §2, Metric Conversion Act 1975 § 205b 1.). Furthermore, entire industires such as semiconductor, electronics, pharmaceuticals, medicine and dentistry, sports (100 meter runs) and the U.S. Military uses metric system extensively if not exclusively in many areas. There are still areas in our life where we do not have nice divisibility by decimal numbering system (which is one of the advantages of the metric system of units) - time (0-24 hours), angle (0-360 degrees), font sizes (Swiss points), aviation / navy, Space industry, etc around the world including nations in Europe. IMO if we had to rewind history and start over again, we should have chosen a base-12 duodecimal system instead of decimal. Imagine how the world would be like if we had 12 fingers: https://en.wikipedia.org/wiki/Duodecimal https://en.wikipedia.org/wiki/Duodecimal One example that always sticks out to me is hearing about German cars being limited to 155mph when of course it's really 250kph. Often you'll find a metric value being quoted as authoritative that's the conversion of an imperial measure though. It wouldn't surprise me at all if that 165cm wide tube was originally set there because something was 65 inches.
