measure something like this.

The "experts" estimate that 11 trillion gallons of water has fallen on south Texas since the storm came ashore with another 11 or 12 trillion expected before its over.

    Mathematics, algebra, and calculus.
    With these tools one can even tell how many atoms are in a gram of a certain substance.

    Sadly the aforementioned language that goes back as far as ancient Greece is slowly becoming extinct, especially in urban areas.

    I wondered the same thing. What more can we expect from people like this that pronounce 'Bayou' like a Cajun (By-You!), instead of like a Texan (By-O). [:D]
    What's next?

    depth (inches of precipitation) X area(the projected precipitation area) = volume(gallons, cubic feet, tons, you pick the unit)

    Remember all those algebra, and calculus classes you had to take & high school that you never used since?...[xx(]

    Well, somewhere there is a knucklehead who had to recall how to do all that math just to try and figure this mess out....[:o)]

    Once again, the experts have confused PRECISION with ACCURACY.

    Could it have been 10 trillion, or 12 trillion, gallons? Sure. No one really knows. The best they could have said was, "An unprecedented amount of water has fallen on Texas."

    The key word, obviously, is 'estimate'.

    Estimating is actually very easy.

    Lets assume 12" of rain on one acre.

    12" x 43,560 sq. feet x 144"/sq. foot divided by 231 cubic inches per gallon gives 325,851 gallons per acre. The number of acres can be reasonably measured, and the inches of rainfall per given acre can be reasonably measured and/or assumed, so the end result is virtually guaranteed to be within an order of magnitude of being correct, and with modern weather algorithms, no doubt much closer than that.

    a really cool rain gauge [:D]
    Make that MANY really cool rain gauges in and around the area being measured. Average them together over time and whaa-laa instant average rain-fall.

    I was in an interview at Microsoft. The interviewer asked me how I would go about counting all the windows in NYC. I told him, I'd take a small sampling, count all the windows in the sample and average the result for the rest of the city.

    The interviewer said it was the best answer he'd ever gotten. I'm sure there are better answers, but that is basically how they calculated the rain total.
    Some will die in hot pursuit
    And fiery auto crashes
    Some will die in hot pursuit
    While sifting through my ashes
    Some will fall in love with life
    And drink it from a fountain
    That is pouring like an avalanche
    Coming down the mountain

    They have this dude, who goes and stands out in the rain for a while. He looks around for a few minutes, hold out his palm for a minute. Then he says...

    "Well, I think it's about...uhhhhhh...eleven, ummmm, eleven trillion gallons...yeah, that's the ticket"

    Then he goes inside.

    "Yep, exactly 11 trillion, it's all good!" [:D]

    Actually it is VERY simple HS math. [8D]
    area times inches of rain (volume in cubic inches) divide by 231 = gallons!!![:)]

    Well, they seem to have measuring fuel into your tank down, so why couldn't they have a meter at the end of the river.

    It's a little paddle wheel with a counter.
