getgrams.cc is a browser-based tool that converts volume measurements to weight in grams for specific ingredients. Unlike generic converters, it accounts for the actual density of each ingredient — a cup of flour weighs very differently than a cup of sugar.
I'm an avid baker who only bakes with a scale.
Ingredient weights are sourced from the King Arthur Baking ingredient weight chart, a well-established reference used by professional and home bakers.
