If you are having your house built by a builder using his feet, make sure no one else comes along and uses their feet.
The FOOT measurement was arbitrarily set by the King, Henry VIII to be exact, and it was His Royal Foot length that was standardized as the measure. One Twelfth thereof was one Inch.
As a young electrician wiring residential houses, we would set the outlet boxes one hammer high off the floor. The works if you are alone. When several guys with several different hammers were in the same house, not so much.
I am searched all the google,try to understand gallons,foot,miles,once etc Because some country use French standards in mainland ,some oceans country like England standard,Now I was get know that,Tack (thank When I measured some thread on Sweden stove The stove looks US international thread standard too Some thread is special too Because I have too bought thread taps
Believe so A horse ass wide is road wide in Rome Road wide change to railway wide in London Railway wide fit for rocket diameter in Florida skybase
@Tantra threads are an absolute horror. I know that saying this does not help you. I cannot think of a better place for information than here. Old UK manufacturers used all sorts of different threads and spread them all over the world. My old motorbike used Whitworth, UNC, UNF, and some special manufacturers own threads. I can only hope that stoves are a bit simpler. When I was at school our exercise books had many many different tables of weights and measures that we had to learn on the back. There is an old joke about “Which is heavier, a ton of rock and a ton of feathers. But there IS a difference (in British measure) between an ounce of gold and an ounce of lead because they have their own scales. I used to measure allotment gardens in Perches and make compost in bushels. We learned all this and we thought that the metric system was far too complicated when it came. Good luck with your stove.
Greetings Tantra. It can be challenging to understand some of what you write, but please, keep writing! I do wonder if the rocket you mention was George Stephenson's steam locomotive 'Rocket'! Riding on its iron rails four feet eight and a half inches apart! Isambard Kingdom Brunel had his own ideas on track gauge, choosing seven feet for greater stability at speed.
@IvanN @Stonehopper There is a bit of a myth, widely debated but which may have some element of truth, that the origin of the bizarre choice of width for the standard gauge was based on continuation of ancient practices, hoorse drawn chariots in the Roman Empire are often quoted.... The theory being that the minimum width for a horse drawn vehicle with a horse between the shafts resulted in ruts being left in roads 4' 8 1/2", and vehicle and carriageway measurements morphed into the first railways.... bearing in mind that horse drawn carriages were often carried on railway wagons with their passengers inside on the early railways, and railways carriages were at first based on road vehicles it may not all be too wide of the mark. At a guess I'd reckon Tantra's comments are that rocket components are limited in size by the railway infrastructure, thus linking cutting edge space technology to the width of a horse's backside thousands of years ago? The other huge advantage of Brunel's broad gauge system was that there was greater width between the locomotive frames for a larger grate in the firebox, and subsequent greater heating area for better efficiency. Designing fireboxes to give good combustion characteristics over a variety of loads while restricted to a relatively narrow width was a headache with standard gauge locomotives until the end of steam! Chris (who has spent more than enough of his life cramped inside locomotive fireboxes with needle guns/riveting equipment, wishing broad gauge had been the chosen standard! )
