  • It has nothing to do with disliking learning. Trying to learn and use a system of measurement without being immersed in it is really hard. For years, I’ve set all my temperature measurements on my phone and thermometers to Celsius, but because I’m surrounded by people and systems that don’t use metric, I have to convert back and forth between the two. It’s a lot of mental effort for basically no gain.

    Every day, customary speed and distance units and my intuitive understanding of them are reinforced when driving and seeing street signs. I know how long a kilometer is, but if you say “My brother lives 45 kilometers away”, I’d have a difficult time truly understanding that. I wouldn’t be able to estimate how long it would take to drive there, for example.

    Another issue is cost. In my job, it would take weeks or months to update all of the documentation and code to metric. Then customers would have to approve of all those changes. A whole bunch of machinery still uses customary units too, so they would have to be replaced or updated.

    I say all of this as a metric lover and evangelist. It’s not trivial to convert an entire massive country to metric. Countries that have converted already should be hugely proud of themselves for accomplishing a difficult task.






  • No, their airlines are not an ancillary product. They are their main product. According to Boeing’s earnings reports, the commercial aircraft segment of the company made up 56% of total revenue in 2018, 42% in 2019, 27% in 2020, 30% in 2021, 38% in 2022, and 43% in 2023. The rest of their revenue is split between the Defense, Space and Security segment, and the Global Services segment.

    Prior to 2017, the vast majority of the earnings for the whole company came from the Commercial Airplanes segment. Since then, that segment has been operating at a loss. Since 2022, both Defense and Commercial Airplanes have been operating at a loss.

    If you’re curious you can look up Boeing’s 10-k form. Page 56 has the revenue breakdowns.
