Frequently asked questions
How many fluid ounces is 100 ml?
3.38 US fluid ounces. That 100 ml figure is worth remembering for a different reason — it's the airline carry-on liquid limit, which US security signs as 3.4 oz.
What's the difference between US and imperial fluid ounces?
A US fluid ounce is 29.5735 ml; an imperial (UK) fluid ounce is 28.4131 ml — about 4% smaller. It compounds at pint scale: a US pint is 473 ml and an imperial pint is 568 ml, which is a noticeably different drink. This tool uses US fluid ounces, matching most recipes you'll find online.
