TJIL literally any size oz, brands are selling waterbottles. Anyone explain why?

  • Most products measured in fluid ounces are actually rounded from ml.

    1 floz is close enough to 25ml that so long as a product is produced in 25ml increments you can essentially find it in integer floz increments.

  • What would be the "inverse" of "you can buy water bottles at any size expressed in whole fluid ounces", and why do you feel it isn't true?
