## Josephson Constant FORMULA

 $$\large{ K_j = \frac{ 2 \; e }{ h } }$$

### Where:

 Units English Metric $$\large{ K_j }$$ = Josephson constant  (See constant value) $$\large{\frac{Hz}{V}}$$ $$\large{\frac{Hz}{V}}$$ $$\large{ e }$$ = electron change $$\large{C}$$ $$\large{C}$$ $$\large{ h }$$ = Planck's constant $$\large{\frac{lbf-ft}{sec}}$$ $$\large{J-s}$$
