Okay but what about the off chance you’re measuring something other than water?

Okay but what about the off chance you’re measuring something other than water?
Estimate as water and fudge it a bit. Conveniently the fudge factor is just the specific gravity and is already tabulated as such in a lot of fields.
But it turns out that water is a pretty good bet most of the time:
- Settled snow is around 0.25
- Dried wood is around 0.5
- Soil is around 1.2
- Rock is around 2.5
Which is pretty good if you want to answer "how much does that truck / ship / mountain / lake weigh?".
Of course there are some anomalies: Tungsten is around 20, but it's not like imperial units help here, and the name literally translates to "heavy rock".
