Metric Cooking από Falk Hüffner

Do you have no idea what "a stick of butter" is, or how to measure "a cup plus two tablespoons"? This add-on provides a button that when pressed, annotates US cooking units with their metric equivalent, while also trying to convert from volumes to weights, such that you can simply use your kitchen scale. Examples, where the part in [] would be added by this add-on:

I used about 1/4 to 1/3 of a cup [60–80 ml]
3/4 cup plus 2 tablespoons packed light-brown sugar [190 g]
1 1/2 sticks chilled unsalted butter [175 g]
a tablespoon of heavy cream [15 g]
2/3 cup freshly grated Parmigiano-Reggiano [65 g]
sides about 2 1/2 to 3 inches [6.5–7.5 cm] high
¾ cup plus 2 Tbs sugar [175 g]
mandoline set to 1/16th of an inch [2 mm].
a 5- to 6-quart [4.75–5.75 l] heavy pot
between 12 ounces and a pound [350–450 g]
at about 350-380 degrees (F) [175–195 °C]
Butter a 13- by 9- by 2-inch [32.5×22.5×5 cm] baking pan

If a recipe page is not annotated properly, please open a new issue at https://github.com/falk-hueffner/metric-cooking/issues/new and provide the address of the web page (you'll need a github account). I will then try to fix it.
