Are US inches different to UK

I heard that my mollies will grow between 4" - 6" thats massive, i've never ever seen them that big

I live in the UK so are the measurements any different to the US,

no, don't think so. I know gallons are different, but I'm pretty sure anches are the same!!

unit measurements of length are a worldwide std
it is only when you get to volumes that you get differences in amounts
and normally only when dealing in pre-metric units
