If i recall correctly there are approximately 28 grams in an ounce and there are 16 ounces in in a pound. 2.2 pounds equals a kilogram. I am sure there must be a simple conversion equation for this.
At .32 cents a gram a 200 gram meteorite would only be about $64 USD so that's not really that bad is 200 grams is all you need.

I don't know for sure if the type of meteorite i saw this past weekend is ideal for pamor, but it was very dense and highly magnetic.
You can easily find it of eBay, but i am afraid you won't find any Pandai there.
