How fun!
The "natural" way to convert bits to grams (ie not based on any specific technology) would be to combine Landauer's Principle and Mass-energy equivalence.

However even then, you still have to choose a temperature (eg STP) which is ultimately an arbitrary choice.
- scatters 3y agoYou do it at the Planck temperature (1.4e32 K), obviously, giving one Planck mass (22 micrograms) per nat, or 15 ug/b. This probably has some physical relevance, but I'm not sure what.
- scarmig 3y agoIsn't that more to flip a bit than representing a bit, though? Another angle might be to look at the Bekenstein bound, i.e. that if you have a physical system of mass-energy m, there's a maximal number of bits B that it can contain. Though that also would need a system-containing volume (surface area?) which would also be arbitrary.

- teddyh 3y agoYou also have to convert mass to weight, and for that purpose you need to choose a gravity, which is also arbitrary.
