I know the ng means nanogram
But I’m curious how would I say the above line of 2.1 ng/kg
For context I got it from this paragraph
a lethal dose of 1.3–2.1 ng/kg in humans
Would it be
2.1 nanogram per kilogram?
Also if I wanted to write that as a decimal number how would i write that?
would not work, as they are no mass unit. 1 mol of Botox does not have the same weight as 1 mol of human (If that is defined at all, as organisms are no pure substances).
Ah, yes good point
