a kilo is the same as 1000 grams, a liter is the same as 1000 milliliters , one kilometer is the same as 1000 meters. I quite know that, I came from a country where the scales are in Kg, Km, Lt.
peace.
I understand standardisation,
But in the field of drug weights, there is room for error which is exploited by psychopaths. See my post above.
I'm not so sure that a litre is a thousand millimetres though? Perhaps a writing error from you?
Drugs have been sold by weight for years, so I am told.
There have been initial imperial weights sold by derivatives. 1 ounce, then half ounce (14 grams) then a quarter ounce (7grams) then an eighth (3.5 grams) then a 16th or 'tenth (1.7 grams) then after metrication, single grams and derivatives of of grams in powder weights. ( as the industry grew and demand and price increased exponentially).
So the weights of sale was also structured. The more you buy the cheaper a thing is.
So a single ounce will have a price each the same price upto 8 ounces. Then a wrapped 9 ounce bar of hash would cost a little less per ounce than the cost of single ounces.
Then next weight cost reduction is at 4 X 9 bars
This is a 'kilo'.
Which is actually 1008 grams
