@ArgonCapital You misunderstood the explanation, what they did was use planks constant to define the kilogram by making an equation for the planks constant that included the kilogram and other units that have already been defined using universal constants
@ArgonCapital Because everything except the kilogram in the equation either is a universal constant, a constant, or based on a universal constant, you can therefore set the equation to solve for the kilogram and arrive at an answer only using constants.
@ArgonCapital So if you view the equation in the video it uses a number, kilograms, meters, and seconds to define planck's(just realized auto correct was changing this to plank) constant. No weight unit except for kilogram involved, so idk where you got that from.
@ArgonCapital I used weight here colloquially, technically there's no weight unit used here at all cause weight is the force generated by mass times g and the kilogram is a unit of mass.
@ArgonCapital Also, as kyle mentioned, you can use E=mc^2 and E=hv by plugging in an exact value for v..... you know what, I'm probably just confusing you lol, I should stop talking about it....
