170 mL to Cups
0.72 US cups, 0.68 metric cups
170 ml is 0.72 US cups, or 0.68 metric cups.
Millilitres and cups both measure volume, so this conversion does not depend on the ingredient — 170 ml of oil and 170 ml of water are the same amount of liquid. What it does depend on is whose cup the recipe means.
