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?

    You can say “nanograms per kilogram.” You could shorten it to “nanograms per kilo.”

    If it were mg/kg, you could say “migs per kig.” You won’t trick me into saying the equivalent for nanograms, though.

    Edit: Not sure what you mean by how to write it as a decimal number. It’s 0.0000000021g per kg. It wouldn’t be standard to give just a ratio of like mass to mass because as others have written it is mass of substance vs mass of patient.
