    Dumbells aren't a calibrated weight, but if you weigh them on a Post Office scale you will have their actual weight. Post Office scales are calibrated regularly and are of high quality, so they are good to use for this.

    Or I could weigh a gallon of water?

    Stop weighing stuff.
    Start filling the tanks with gas and diving them.
    All you really care about is how long they'll last you, with your gas consumption range, under various situations.

    OCD for sure.

    My previous comment hopefully snapped you out of it.

    The big picture is, what is your SAC rate for those particular tanks in psi per minute under various conditions of temperature and work rate.
    All you need for that is average depth and psi used, then correct to 1 atm/surface.

    All the weighing is a waste of time.

    I thought the goal was to identify the tanks?

    Really I want to make sure the tanks we own are not some abominations which should be destroyed before they kill us.
