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?
0.0000000021g/kg
or 0.0000000000021kg/kg, if you wanted the same units both sides…
( I’m presuming this was your last-line’s request )
