I sometimes use Maggi liquid seasoning in my cooking. My recipe calls for a specific number of grams to be added.
The other day, the supermarket was out of stock of the liquid seasoning, but they had these cubes:

Now my problem is, how do I add the right amount of seasoning to the recipe? There is no indication on the packaging, or advice on the internet that I can find.
How much water should one cube be dissolved in to make it the same concentration as the liquid seasoning?
