What is dl stands for?

Dl stands for a 10/part of a liter, or 100ml
hope you got it, Birthe in DK

Dl stands for deciliter, that is, one liter (l)divided by 10, which is equal to 100 ml (mililiter).
2,5 dl = 250 ml = 1 cup = 8 fl oz;
1 dl = 100ml = 3 1/2 fl oz;
1,5 dl = 150 ml = 5 fl oz;
2 dl = 200 ml = 6 1/2 fl oz;
There is a site where you can do conversions http://www.convertunits.com/from/ounce+[UK,+liquid]/to/ml
I hope this helps.
