Dear [[CUlator]]
Thank you for your comment.
The part of the discussion you are obviously referring to is, computing the same quantity of mass using two different systems, imperial and metric, through E=mc<sup>2</sup>.
You have not done this. You only divided one constant by another (speed of light & acceleration of gravity). On the metric side of your example you convert the squared light speed (which is the same in both systems because it's the distance light travels in a second squared), to the imperial system before converting ft/lb to Joules. You did not use E=mc<sup>2</sup> to calculate equal quantities of mass using metric and imperial systems.
The discussion is about E=mc<sup>2</sup> and arbitrary systems of measurement with no correlation. Even though calculating different systems through E=mc<sup>2</sup>was a side issue to the discussion. I maintain that when using E=mc<sup>2</sup> to compute equal amounts (0.453kg and a pound (lb)) using the imperial and metric systems. The answers will not be the same. The answers will be in calories and Joules. Then convert calories to Joules.
But most importantly, you ignored the thrust of the discussion, which is: Arbitrary values cannot validate the tangible. On one side of the equation is Energy, which has a precise amount per given mass. On the other side of the equation are manmade units of measurement with no relationship to Energy contained within mass. When humans decided what value to assign to a Joules, they assigned the amount of energy used when applying a force of one newton through a distance of one metre. This has no relationship to Energy contained within mass. Until the twentieth century, burning was used to release energy from mass. This is only a tiny percentage of the potential energy. With fission in twentieth century a lot more energy per mass was released, but still only a percentage. In the future, probably hundreds of years, even more energy will be released using methods undreamt of at present. The Energy per mass and if different types of energy co-exist within mass is unknown and will remain unknown for many years! So how can an equation using arbitrary units of measurement quantify the unknown?
I look forward to your reply
