If I didn't understand them they wouldn't be irritating.
You really can't be this thick, Ray. a- I haven't been around longer than New Zealand nor as long as the USa's measurements. b- Why would I become aware of the USa's non-standard measurement systems being non-standard when I was ten years of age? (year five) After all, you use the same measurement _terms_ for measurements which _are not_ the same as the internationally used "Imperial" measurements. From distant memory, the first inkling I had of that situation was in reading old US MR magazines which discussed modelling 55 gallon drums, a volume which, AFAIK did not exist in New Zealand. c- why would you stupidly imagine I haven't come to grips with them? d- The important point; you use the same terms as Imperial measurements without bothering to define _which_ measurements youare refering to.
Obviously you don't understand computer programming - just another area of your extreme ignorance.
