Louis: You quoted the wrong person. That's what Adrian Jadic wrote. If you got it from my message, that was where I was quoting him.

To complement my previous message, I should have given the definition of "(measurable) quantity" : Quote : (measurable) quantity "attribute of a phenomenon, body or substance that may be distinguished qualitatively and determined quantitatively. Notes : 1 - The term quantity may refer to a quantity in a general sense [see example a)] or to a "particular quantity" [see example b)] Examples a) quantities in a general sense : length, time, mass, temperature, electrical resistance, amount-of-substance concentration. b) particular quantities : - length of a given rod - electrical resistance of a given specimen of wire - amount-of-substance concentration of ethanol in a given sample of wine. 2 - Quantities that can be placed in order of magnitude relative to one another are called "quantities of the same kind". 3 - quantities of the same kind may be be grouped together into "categories of quantities", for example : - work, heat, energy, - thickness, circumference, wavelength. 4 - Symbols for quantities are given in ISO 31 Unquote The book giving these definitions was drafted after the product of a working group of experts from BIPM, ISO, IEC, IUPAC, IUPAP, IFCC, OIML. Now given all of that, I am not sure wether "liter per flush" is a unit of measurement. BTW, my dual-button toilet gives 4 l/fl or 8 l/fl depending on the button you activate. Louis
