BBC: "the size of a five-storey building and weighs approximately 4,000 kg (630st) on Earth". "630st" - stone age measurement units for space age technology is not a good idea. #MoonCrash #BBC

The use of stones in this context strikes me as just perverse. In my early experience, stones were generally used to indicate the weight of people and potatoes. 4 000 kg is 4 tonnes, which is so close to 4 imperial tons, that it’s the only one we use, even on our benighted traffic signs !

The empty upper stage has a *mass* of 4,000 kg - on Earth AND in space. That's the beauty of #metric - separate units for mass and weight - avoids confusion when talking about objects subject to different gravitational forces. #MoonCrash #imperial #BBC www.bbc.co.uk/news/article...
