As much as Elon Musk despises US customary units, there are still some aspects of SpaceX's rocketry that use customary fasteners, customary drill bits, customary plumbing connectors, customary milling machines, etc. | |

Despite what some condescending Europeans would have everyone believe, US Customary units are still widely used in industry. | |

Eventually they came around, the ISS is metric. The ISS is also part Russian, part European, part Japanese... the US section of the ISS mixes metric and English units, and NASA generally to this day continues to use a mix of units for other vehicles and missions. They're not done coming around just yet.

Time pressure certainly was the case through Apollo. But the Shuttle had a generous development period. Was the factor there that the Shuttle was seen as an aircraft, and therefore be tied to standard aviation units? | |
