    Mercifully, g=9.8 everywhere on Earth’s

    Big nope. It depends not only on height, but also on density of stuff under ground.

      I’d say it’s more of a “small yes” than a “big nope.”

      While gravity does vary, it goes from about 9.76 to about 9.83.

      All of which does, in fact, round to 9.8

          Everything experiences different gravity (and “apparent gravity”) in space. We should pass a treaty of using metric only there, if only to avoid losing more spacecraft.

      The pedantry in this post is so dense you would need a torch to cut through it

      What’s the variation? Does it ever get to 9.9 or 9.7? It’s a negligible “nope” for people weighing themselves :D

      We already have a permanently inhabited base outside Earth (ISS) with effectively zero gravity and there might be one on the Moon or Mars in 100 years. We should pass treaties to only use metric in space – a probe has been lost to unit confusion already.
