Do not read 8.57 stone as 8 stone 57 pounds
This is the mistake I see most often with decimal stone. The decimal part is a fraction of one stone, and one stone is 14 pounds: 0.57 x 14 is 8 pounds, not 57. That is why this page shows both forms side by side. Writing 8 stone 8 pounds leaves no room for doubt, and the decimal 8.57 does the same job in a single number. Pick whichever your form or scale expects.
