Why we ask for units every single time, with three examples of what goes wrong

Post #17 and I disagree about the size of the effect, not about the direction.

Avoid "any advice?" at the end. It is so generic that people do not know which part of the post it refers to. Pick the specific part and ask that specific question instead.

Somebody will have a better source than mine, and I hope they post it.

Do not apologise in the first line. It costs you the space where the question should be, and nobody here thinks a question is an imposition.

Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

If that is already documented somewhere, ignore me and link it.

If you are asking about a document, quote the exact wording of the line you are asking about. Paraphrasing a specification is how a discussion ends up about a document nobody has read.

Speaking as somebody who asked badly last month and got a polite request for four missing details: writing the question properly the first time takes ten minutes and saves two days. Learn from me.

This is the sort of thing that ought to be settled and apparently is not.

Adding the measurement that post #97 says would settle it.

Staff note on titles, since it comes up. We retitle topics fairly often, always leaving the original in the first post and always logging it. It is not a criticism of the wording — it is that a title is how somebody finds this in eighteen months.

Units. Everything needs units. This is why we ask every single time. I have seen the same arithmetic done three different ways depending on whether the person was thinking mg/mL or mg/dose or something else entirely. Stating the units makes that impossible.

I have kept the units in throughout, for the obvious reason.

This follows post #111 rather than contradicting it.

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

The honest answer is that it depends, and here is what it depends on.
