How can i convert 180 kPa to flow rate say ml/min. Many thanks.

There is no formula for this conversion. You have a pressure at the head of a column. If you measure the output flow at this pressure you may be able to estimate the flow at different pressures.

You can use a software to do the conversion.
The carrier flow at a given inlet pressure depend on your column dimensions (lenght and ID), oven temp and type of carrier gas.
We have a freeware called "flowcalc" which is very usefull.
I think you can download it from agilent webpage
