Don, I don't think the metric system is sane!!! I have found out what 5 and
8 meters is when it comes to the length of antennas but I now have the
conversion bookmarked in favorites!!

OK, I missed 4 and 20, but I was making a practical point, not a
mathematical one so I deliberately left 1 and 100 out!

Don,
As a lover and rebuilder of old cars, I find I have ASF, BSF,
Whitworth, BA, Metric and adjustable wrenches (spanners).
Not to mention Bristol keys, Torx wrenches and other efforts
at 'modernisation'
But my garage would seem a lonely place without them :-))
Only Metric??? Heavens forbid

A group of French scientists decided that 1/1,000,000th of
the distance from the north pole to the equator would be the
new standard for all of Europe.
I recently completed the construction of K2 N4 4875 and it works very well!
Last year, I built K1 nr 1875 and I now realize that I wound ALL its toroids
with one turn too much!
But K1 works OK
Would I gain anything by correcting my mistake and rewinding the toroids
with the proper number of tu
They call it the 'English' system, but even the English folks now measure

Like it or not, the US is still using feet and yards, not centimeters

the metric system. However, we don't typically have meter sticks

No. You can't have half a turn on a toroid. It's only an extrsa turn if

If a toroid has been wound backwards, it is best to strip

I, also, am very right handed. I wound the toroids without much thought

That's correct. There are no partial turns on a toroid.
