A water bottle is labeled 500 mL — how many fluid ounces is that?
Frequently Asked Questions (FAQ)
500 mL equals approximately 16.91 fl oz (500 ÷ 29.5735) — just over two US cups.
1 liter (1,000 mL) equals approximately 33.81 fl oz, which is why standard 1-liter bottles are often labeled "33.8 fl oz" in the US.
This usually comes down to US vs UK (Imperial) fluid ounces — 500 mL is about 16.91 US fl oz but about 17.60 UK fl oz, since the UK fluid ounce is smaller (28.4131 mL vs 29.5735 mL).
Divide the mL value by 236.588 (the number of mL in a US cup) — 500 mL ÷ 236.588 ≈ 2.11 cups.
This calculator uses the US customary cup (236.588 mL) throughout, since that's the standard for US recipes and product labeling.
