the End of the World
This morning my Withings scale is telling me it's going to be hot, "the-end-of-the-world" kind of hot.
That's today's weather on Venus, not Earth. You're not missing out though, it's very monotonous and boring over here: acid sulfuric storms everyday .
Anyway, this brings about 2 features of that scale: geo-located weather as shown in the picture, and geo-located gravity force, or what Withings marketing team calls "gravity compensation" , i.e. it adjusts the weighted value with the local gravitational acceleration value to derive your mass (remember W = m*g)  .
Does "gravity compensation" matter?
"Not at all" that's how much it matters. Because you only need precision , that is repeatable and reproducible measurements.
...Unless you're also in my case, regularly commuting between Earth and Venus and taking your scale wherever you go.
