  • What about the children
  • What really annoys me is when I dispense exactly the amount I want to pay for eg £20 then by the time I get the hose back it has rolled over to £20.01p. Does this mean I am being scammed ;)

    Petrol pumps are subject to Weights and Measures Act monitored by Trading Standards. IIRC they are legally required to operate within +0.3% to -0.3% on a minimum delivery of 2 litres.

    How many of use weigh the products we buy at a supermarket. Most suppliers will over weight a product rather than risk fines. So your 1kg of flour will often weigh 1015g.

    There will always be human error, faulty equipment and in-date calibrations that go wrong. But equally customers can benefit:

    Which is why I'm resisting getting smart Electricity & gas meters.
    My old mechanical meters will have been manufactured to under read in my favour by a few %.
    The new smart meters will be more accurate, so I can only lose out.
    1 or 2% of a £1200 energy bill is worth saving.
    I want to go back to The Olden Days, when every single thing that I can think of was better.....

    (except air quality and Medical Science ;))

    What makes you think they will be more accurate?

    Acts of Parliament and official bodies involved.

    It's not a scam. It's a conspiracy.

    That is a software error, it wont affect the base accuracy of measurement.
    I would have thought in the 21st century they could be made more precise, and set a lot nearer the actual value, but I could be wrong (or is it right?- everything was better in The Olden Days).... :rotfl:

    I think perhaps you're confusing precision with accuracy.

    A £5 digital watch may be more precise than an analogue Rolex, but it's unlikely to be as accurate.

    The meaning of precision changed recently, from what we would now call resolution, to repeatability/reproducibility/lack of random error.

    A precise measurement is repeatable, so you can calibrate a precise instrument to be accurate, then we are talking about "trueness" of the results.


    So in the case of the rolex, it will be precise if every 24hours it reads exactly the same time, but it won't be accurate if I don't set the time to match a standard.

    I haven't used a Sainsbury's Petrol Station for some time now as I no longer live near one however somewhere on their pumps there'll be a Trading Standards sticker from the testing they carry out.
    It's not your credit score that counts, it's your credit history. Any replies are my own personal opinion and not a representation of my employer.
