How many to the tonne?
Out of curiosity, I weighed an SD card in my desk, inc. packaging - a tad over 7 gm, which works out at about 140,000 to the tonne. (only 1 gm without the packaging)
How many to a standard container, I wonder - and what's the cost to ship one chip from Hong Kong or Seoul? The best part of not very much, I'd guess. Cheap as chips?
