Good point about being natural rather than tied to base 10. Though natural conflicts with human convenience and ultimately is is for humans. Even more natural could be using the same unit for mass and energy, and make it dimensionless!
- saalweachter 2y ago2^64 daltons (30 micrograms) is already about 2 gigajoules. 4!! photons -- specifically the 21cm photons corresponding to the hydrogen line [which, speaking of precision, we have the frequency of that down to around 1 part in ten trillion] -- is about 0.6 Joules. So 4!! hydrogen atoms gets you about 1 gram, 4!! H-I photons gets you about 0.6 Joules, and the wavelength of the H-I photon is around 21 cm.
