So... a 7,500 KVA transformer = 7.5 MVA transformer, right?

The "M stands for one million. The "K" stands for one thousand. That's why Basra's formula works.

It is a small k (kVA)

Zog,

That's the way I learned it, also.

Inside a sentence the "k" of kVA is like any other first letter of a word.

V is short for Volt, a man's last name;

A is also short for a man's last name, Ampere.

Being short for proper names, "V" and "A" are capitalized.

His name was Alessandro Volta.

The "V" and "A" do not stand for names, even though the words they represent were chosen to honor two persons. The letters stand for the common words (not proper words, not capitalized) "volt" and "ampere." The authors of many textbooks have chosen to use capitalized letters "V" and "I" to represent the phasor quantities of voltage and current, and the lower case letters "v" and "i" to represent the same quantities as functions of time. The letter "A" (or "a") is not used to represent either current or amperes. It is only used as part of the symbol for apparent power (VA) or the symbol for reactive power (VAR), with or without a preceeding quantifier (e.g., "K" or "M" or "G").

The lower case letter k" is used more frequently to represent "kilo-," but it is not incorrect to use the upper case "K."

Oops. Thanks, Charlie. :o So much for my learning and/or my memory.

The US Nation Institute of Standards and Technology has some very interesting reading about the International System of Units (SI). It does state the “k” prefix is lowercase. The “A”(a basic unit) and “V”(a "specially named" derived unit) are officially uppercase when referenced in a formula. I usually don’t make a big deal about either issue except in technical papers.

One of the most fascinating things to me is that most of the basic SI units (meter, kilogram, second, ampere, kelvin, mole, and candela) have been defined or officially redefined in my lifetime
