Cells per microliter to cells per milliliter
Type a value in cells/µL to get it in cells/mL instantly.
Nothing on our list is smaller: a freshly inoculated culture is 10× denser. A 10 mL culture at that density holds about 10,000 cells.
Convert the other way: cells/mL to cells/µL
What it means
How dense is that culture?
Conversion factors are rules of thumb for a 1 cm path length. They differ between spectrophotometers, strains and growth phases, so calibrate your own.
The math
How to convert cells/µL to cells/mL
To convert cells per microliter to cells per milliliter, multiply by 1,000.
Example: 1 cells/µL × 1,000 = 1,000 cells/mL.
In the other direction, 1 cells/mL = 0.001 cells/µL.
The table below is for E. coli (8 × 10⁸ per mL at OD 1).
