microgram per millilitre
Mass concentrationexact by definition
One microgram in one millilitre, which is numerically the same as one milligram per litre. It is the biochemistry and microbiology form — protein assays, antibiotic potencies and cell-culture supplements are written this way because the volumes handled at a bench are millilitres rather than litres.
Watch out: µg/mL and mg/L are the same number, and the two are used side by side in the same laboratory without comment. That is genuinely safe. The dangerous neighbour is µg/L, which is a thousand times smaller and only one character different in writing.
