The Ampere went from being the thought experiment of two infinite wires 1m apart creating a certain force to being something nearly unintelligible to the average person.

The ampere is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 × 10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆ν

Indeed, I can't even parse the sentence.
