Setting Column width in Apache POI
===

I m writing a tool in java using Apache POI api to convert an xml to MS Excel. In my input xml I receive the column width in points. But the Apache POI api has a slightly queer logic for setting column width based on font size etc. (refer [API docs](http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFSheet.html#setColumnWidth%28int,%20int%29))

Is there any formula for converting points to the width as expected by Excel? Has any one done this before?

There is a setRowHeightInPoints() method though :( but none for column.

P.S.: The input xml is in ExcelML format which i have to convert to MS Excel
