Milligrams per milliliter to micrograms per milliliter
Type a value in mg/mL to get it in µg/mL instantly.
1,000µg/mL
That's about the same as a working solution. A 20 µL sample at that concentration holds about 20 µg of protein.
Convert the other way: µg/mL to mg/mL
What it means
How much protein is that?
A280 assumes a 1 cm path length and a protein with ordinary aromatic content. Nucleic acid contamination absorbs at 280 too and inflates the reading.
The math
How to convert mg/mL to µg/mL
To convert milligrams per milliliter to micrograms per milliliter, multiply by 1,000.
Example: 1 mg/mL × 1,000 = 1,000 µg/mL.
In the other direction, 1 µg/mL = 0.001 mg/mL.
The table below is for Unknown protein (A280 = 1.0 per mg/mL).
