units has (I assume room temp/pressure) densities for all elements, as well as some precious metal prices and currency exchange rates (you need to run the units_cur program regularly to update the database for these). It also has tab completion to make discovering these a bit easier.
The invocation is
You have: goldprice * golddensity * spherevol(10cm/2)
You want: GBP
Neat! Thank you!

TIL -- thank you, brother!
You can just save a step and ask ChatGPT the answer. It can google
the current spot price of gold.
Sure, but then I need to do all the math to verify the answer it gives me isn’t gibberish anyway.
What if its wrong
You can just save a step of double-checking everything by using WolframAlpha

Is there some trick to this? Or do you have to input it like:
You have: 4/3pi(10 cm)^319320 kg/m^345000 GBP/kg
