If Planck's constant, instead of being \(\displaystyle 6.63 \times 10^{-34}\) J s, were 1 J s, how would the universe be different?

Consider also that most equations about the quantum "world" are based on the fact that h is so small. If h were large then most quantum events would be the norm. So, for example, wave-particle duality would be common.

One of my professors made a joke that we would get an A in class if we could quantum tunnel into the final exam. If h = 1 Js you could bounce back and forth in the hallway and actually do it.

In the usual MKS metric system is $\displaystyle h= 6.63\ 10^{- 34} \frac {k\ m^{2}}{s}$. In principle You can use a 'quantum metric system' $Q_{m} Q_{k} Q_{s}$ where is $\displaystyle h= 1\ \frac{Q_{k}\ Q_{m}^{2}}{Q_{s}}$ and in this case it would be...

$\displaystyle \frac{Q_{k}\ Q_{m}^{2}}{Q_{s}} = 6.63\ 10^{- 34} \frac {k\ m^{2}}{s}$

... and I don't know if such a metric system is very comfortable in our quotidian life ...

Kind regards
