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?
A quick Google of the numbers says OP is likely talking about botulism so I guess they perhaps have been reading about Botox
Close was talking about Clostridium botulinum
Botulinium
