You have specified neither the quantity nor the unit of the amount 2.9 x 10,000 which is said to be "per ul" (per microlitre).

So no conversion is possible.

To convert that 'whatever' to "per ml" (per millilitre), you have to multiply the amount by 1,000.

So your answer will be "per ml", (but not ng / ml, which is nanogram per millilitre).

In notations and conversions, one must use consistent symbol l for the litre, the unit of volume (or L, for the Litre, as Americans seem to prefer).

If, for example, you convert from ng / ul, to ng / ml, then the value will be (2.9 x 10,000 x 1,000 =) 29,000,000.

If you convert from pg / ul (picogram), to ng / ml, the value will remain unchanged, viz. 29,000.
