the English and American "billion" was harmonised many years ago

Can you give a reference for that? I haven't found one.

Thank you, that clarifies the situation. The English Billion still
exists but in 1957 British Ministers were told to use the American
meaning as it was considered "International" by the then Prime
Minister.

Obviously it cannot be completely international if there are still

And languages. Spanish, in Spain at least, a billion is a million
million. So one has to be careful when translating.

All this abundantly demonstrates that we're better off using the metric

Or notations like 5*10^9 or 5E9 (calculators did this. Do they still
do? 5E9 is very simple)
When you deal with RF it's essential to have a scientific calculator that
can handle exponents like that. I continue to be amazed at the computing
power they're capable of for next to no money. In real terms they're a
fraction of the price they were when they first became available. The
first ever scientific calculator I ever had was an HP one. A friend had
the Sinclair one. Another had a Bowmar (they went bust around 1975 IIRC).
They were a quantum leap over what we used beforehand.

I hated HP calculators with their reverse polish notation. I bought TI
instead, or Casio later.
RPN is wonderful. Nested parentheses are a mess.
What resistor do you put in parellel with 12K to get 7K? That takes 7
keystrokes on my HP32.
My first calc was an HP9100. It cost as much as a new Chevrolet. Then
I got an HP35 and a Honda S90 motorcycle; the bike was cheaper.
I still have both calcs. Someone stole the bike.
