Hi,
I have just a question, about how to write electrical units

Do you not use the international standard system of units?
The SI system is an international agreed and standardized system. It is
used in many countries to make an end with the unit mismatch, at least on
technical area.
I declare what I mean:
For electric current (ampere) the unit is A (neither Amp nor amp)
Here you would write
<<40 A>>
A is every times capitalized.
Everybody here in Germany and in many other countries would recognize it
without any difficulties.
Another example:
I = 40 mA (this is 40*1/1000 A)
I = 40 A (I is the sign for electric current)
To avoid misunderstanding it is important to use the correct unit.
I thought, A is international, now I see, the English speaking world does
not use it? Is this right?
I must revise my knowledge about units this way. :-(
I learned, that a space ship lost its route because of ambiguities in
measurement between several systems.
