Explanation
This is the reverse water-only side of the same conversion basis. It turns US fluid ounces of water into grams using the standard kitchen approximation that water is about 1 gram per milliliter.
That makes it useful for questions like how many grams in a fluid ounce of water, shot-style water pours, and bottle-style references where the starting point is volume but the target is grams. The mirror page reverses the same water basis to estimate fluid ounces from grams.
