What is the meaning of 'e' written after the volume amount.

Question

Normally on juice or certain other items packs, 'e' is written after the volume or gramm description. e.g., 500ml e. or 1000g e. why ?

Answer 1

yup to answers above cause in statistic way the exact volume or mass will like almost never be 0,5000 liter but like 0,5060 or 0,4955 liter etc so sometimes a bit more sometimes a bit less so 0,5 liter should be the avarage but there will be a standard error, like a Gauss curve:)

Answer 2

the e normally means that the measurement is a Net measurement not a gross measurement i.e. just the contents and not the contents and the packaging together.

Answer 3

The e means estimate. It is included to prevent complaints if the mass or volume is not exact.
