50 grams is equivalent to:

• 1/5 cup or 1 3/4 oz of water
• 1/4 cup or 1.8 oz of water
• 1/4 cup of water

Its important to note that grams and cups are not interchangeable units, as grams are a mass unit while cups are a volume unit. The exact conversion rate from weight to volume can vary depending on the ingredient and its density, so its best to use a kitchen scale for more accurate results in cooking.
