There were some people at my university for whom it was a science question. And they paid about €1350 per gram and the first thing they did with it was dissolve it in sulphuric acid.

This was posted in a weed community first and then crossposted here. Because for a stoner the important question is "how much does a gram of weed cost?". For a scientist, more importantly the question is "what system of measurements do you use?", or, specifically, "how much [mass] is a gram [in your unit system]?"

But (taken literally by my autistic ass) it's one we already know the answer to because we're the ones who defined all the units in the first place. A gram is a unit of mass, not weight, which is why its value is the same regardless of the value of g. That's also why it's always measured with a balance rather than a scale. It's based on the Planck constant -- which is, well, constant.
