    To convert F to C, subtract 32 and then multiply by 5/9. To convert C to F, add 32 and multiply by 9/5. If that's not cumbersome, I don't know what is; In the US, that is taught in the 5th grade (I think). By summer break, we all forget about it.

    I agree, and I'm an old fart from America! Who can't multiply by 10, 100, or 1,000? Water freezing at O C. and water boiling at 100 C. Easy! As far as how something is spelled (spelt), or pronounced, I don't think it matters. Spilt milk! Or is it spilled milk? Who cares? My dog's name is Phydeaux.

    By using the word intuitively, I meant that Americans can pretty much tell how long a foot is by holding their hands apart. They can come close to knowing when there is a pound of something in their hand. I did not mean they know how many feet in a mile or any other kind of conversion. The metric system makes total sense, but Americans will not intuitively know when they are holding 1 kilogram in their hands etc. They, like the Brits, will just have to get used to it.

    My young American grandson has trouble pronouncing aluminum, but he has no problems pronouncing aluminium. Being a 70 year old American, I can remember going to the "theatre" as a child . It was spelled that way in the U.S. then. To me, theatre seems the correct way to spell it, because that is what I was taught. In any case, I find the whole discussion to be unnecessary. We all believe that we are correct, and this is directly related to where we were born. Neither is correct, nor incorrect. In the end, all of us know what the other is trying to say. It just bugs us somehow??? Now, the metric system is another thing entirely! Americans intuitively know what a pound feels like, or how long a foot or mile is. However, it is much easier to multiply by a 1 with zeros...see more »My young American grandson has trouble pronouncing aluminum, but he has no problems pronouncing aluminium.

    How to Build Circuits

    For me, conventional current flow confuses things. I learned electron flow in the USAF in the early sixties. The concept of electron flow makes more sense to me because electrons actually carry a negative charge, which is a tangible. An electrically positive charge is really just a point where there are fewer electrons (a void) than the negative point. I agree that unless you are talking about actual earth ground, it tells us little. I like to think of charges as less negative, or more positive. For ex., -5VDC is positive relative to -10VDC. We had several different grounds, such as earth, chassis, vase, circuit, utility, etc. They were not always at the same charge electrically (Scary on vacuum tube circuits). I am not sure what the military teaches now.

    Quick and Easy Jacobs Ladder

    You really cannot blame just one aspect of electric shock resulting in death. I (Current, aka amperage) times E or V (Voltage) = Watts (power). Lightning is very high voltage, but low current, so the overall power in watts is low, but it can still kill you. 120 volts at 10 amps = 1,200 watts of power and can also kill you! Think of voltage as pressure and current (Amps) as the tangible stuff like water or BBs. A BB with lots of pressure driving it will do much damage. A 2 pound cannon ball (Amps) with a relatively small amount of pressure (Volts) will also do some damage. The overall power (Watts) can be the same for both the BB and the cannon ball. Think of the damage a micro meteor traveling at 25,000 plus MPH can do to a satellite, as will a 2 pound mass going 25 MPH.

    Walk-in open air chicken coop

    Definitely agree with other posters on burying wire at least 18". Chicken wire comes in 1" hole size also. Put some of that, or 1/2" hardware cloth, over the existing 2" wire from the ground up to 3 feet. Weasels can easily squeeze through 2", snakes too. The bottom sill should be pressure treated or redwood. Not sure why you turned the studs on edge?

  • How to Scramble Eggs Inside Their Shell - NEW VERSION

    One method uses a paper clip bent to form the shape of the number 7. Poke a tiny hole in the end of the egg, and then insert the short leg of the wire into the egg and then spin the long leg using a drill, or? The hole won't leak egg during boiling.
