side bar here:
since you're using metric & imperial for these calculations..
is this imperial gallons or US gallons?

( I always wonder which it is that you guys are actually using... it's so confusing...lol)

Even though beachcals says metric or imperial Michael stated in one of his posts that it is US gallons. He said he will fix that in the next version.

Okay great,
I was specifically refering to the calculations on the previous page of this thread...
( Mls to Gallons & such)

- so when people here say, " my pool is Blah Blah gallons", they mean US Gallons (?) & that is the standard measurement for you USAers?

good to know; Us Canadians get a wee bit confused on the whole gallons issue

[waterbear]

another good reason why we should have all gone metric years ago!

I agree 100%
I can't fathom why the USA wants to keep up this old system,
it makes calculations quite difficult, particularly when comparing to international testings

I was using and assuming U.S. gallons in my calculations. In my spreadsheet I have a switch for metric so instead of U.S. gallons its liters. However, should I also have something for Imperial Gallons? Is that commonly used for pool volumes in the British (shrunken) Empire?

My understanding is that if you are part of the " commonwealth" then you use Metric
...
I was a travel agent for a bit ( one of the many things I've done...lol), & I can't think of anybody else ( off hand) that uses imperial over metric ( other than the USA)...

I believe the scientific community has chosen Metric. period. (lol)
