No. 300g of water is 1¼ cups, while 300g of all-purpose flour is 2⅜ cups. Same weight on the scale, different volume in the cup, because the two have different densities.

Weighing is more accurate, especially in baking, because it removes the variation in how the water is packed into the cup. If you have no scale, use the cup figure above and keep your measuring method consistent across the whole recipe.
