Dont care, not the point. The calculator states water capacity, as did my answer and it was partially to correct the misconception that just because youre working in imperial you HAVE to know the working pressure of the tank..
Besides, I think Ill stick with metric anyways, Its far easier to deal with
Water capacity vs compressed air capacity really isnt about metric or imperial though, both can be expressed in either..
I would suggest you have radio buttons at the top of the page to select imperial or metric globally for all of the calculators.
It is unlikely that a user would use metric for one calculator and imperial for another, so this will allow them to select a mode to work in and will remove the awkwardness of having to say things like 10m (33').
Also, I think it would be a good idea to build a phone app for this that doesn't require an internet connection. People are commonly out of cell phone range at dive sites.

ROFLMAO. Too funny.
If you weigh165 lbs's and your exposure suit is a3mm wet suit and your air tank is made out ofsteel and you're diving in salt water,
then you'll need approximately15lbs (+/- 2kg)of weights.
To answer your question, I'd say it's not even remotely close. If I use an Aluminum Backplate with a steel 100 in this configuration, I don't need any weight. Your formula don't take into account body fat vs muscle mass... All of that aside, I wouldn't comfortably recommend to a student in a jacket BCD with a 3mm wet suit (which has foam and is buoyant) with an Aluminum tank to wear 15lbs of weight... 12 Lbs maybe as a starting point? But with Steel, probably not.

Says I should be using 31 lbs of weight. I use 18 and could probably do with 16.

Dangerously incorrect on weighting - 11 pounds in error for my information. Also found other errors..........

Weight calculator is about 25% over in swimsuit, 50% over in 3mm. I didn't look at the other options.
The SAC rate is only in metric and should have an imperial version using cubic feet and PSI.
In fact all calculators should included imperial options (feet).

As others have stated the weight calculator is way off and in some instances dangerously so. Putting some numbers in from my latest dive class the calculations were off by 20% at best and well over 50% at worst. In other words a useless answer.
