Description

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

Turns everything into ml. Then I have to search again how much is it in grams. Not really useful.

Slow, buggy, and only worked for one out of the many, many American measurements in a recipe.

A good extension that I would love to use, but why on earth does it insist on turning volume into weight? That would be a great optional feature for people who want to use their scales, but making it mandatory renders the whole extension basically useless for those of us who don't. Add a setting to switch to strict volume-to-volume conversions and it's an easy five-star. Other option that would be nice are forcing dl instead of ml and disabling conversion of volume measures other than cups. Where I live, we have dl instead of cups and otherwise use essentially the same measurements, so seeing that 1 1/2 cups is 350ml is slightly annoying because I'd rather have it as 3.5dl, and specifying that 2 tablespoons is 30ml is just unnecessary clutter.
