I like to feed our garden birds and buy large sacks of mixed seeds from Aldi, the well known German discounter. When they are not instore they will send them mail order.https://www.aldi.co.uk/wild-bird-seed-m ... 9277266800
Their seed comes in sacks marked 12.75kg and I often wondered why that quantity.
10kg, 20kg maybe even 12.5kg would give an integral number of sacks to the tonne.
But 12.75kg?? A few key presses on my phone shows this is almost exactly 28 lbs or 2 stone which is 1/80 of an imperial ton.
Antiquated or what? Strange to see this from a German company.
I have no problem working in imperial units and several of the conversion factors are burnt into memory from my childhood when dual weights were starting to be printed on food containers and I used to like stretching my mental arithmetic skills checking the factors.
