            double fontHeightPoints = pdfObject.TextProperties.FontHeight;
            // Convert to inches: 
            double fontHeightInches1 = fontHeightPoints / 72.0;
            // Or use PDFDocumentPage.ConvertPoint to convert to inches:
            PDFPoint pt = new PDFPoint(0, fontHeightPoints);
            double fontHeightInches2 = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Inch, pt).Y;
            // And pixels:
            double fontHeightPixels = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Pixel, pt).Y;
