Density of the metals and woods is pretty useful on that site. It lives in my bookmarks. However, they do not provide conversions in any unit other than the kilogram per cubic meter and we live in US. Therefore we needed a density unit converter site..

Upon some research I found that they have included all of the materials, woods and metals on the above site in an easily convertible fashion at this density converter page -> Online Density Units Conversion Tool (http://easyunitconverter.com/density-unit-conversion/density-unit-converter.aspx)

Hope it helps everyone...
