Well, what I meant with that, is that it’s semantically important that it’s ng of the substance
per kg bodyweight
.
If it was ng of the substance
per kg of the substance
, then in proper mathematical physics, the unit would disappear completely.
So, for example:
42000000000 ng of the substance
/ kg of the substance
Is equivalent to:
42000000000 * 0.000000001 * kg of the substance
/ kg of the substance
Which means in the end, you just have: 42
As my physics teacher would often say: Is that 42 potatoes or sausages or what is it?
A number without a unit is just devoid of meaning…

would not work, as they are no mass unit. 1 mol of Botox does not have the same weight as 1 mole of human (If that is defined at all, as organisms are no pure substances).

Ah, yes good point
