Another pedantic remark is that people use $1K instead of $1M to mean $1000.

I think it's fine to use whatever it takes to get the message across.

Which stands for kilo and is correct.

[ph0rque]

Lowercase k stands for kilo; K stands for Kelvin (as long as we're being pedantic).

It is uppercase in the comment above.

And a letter can stand for multiple things, from temperatures to chemical elements to whatever.

As long as we're being pedantic, that is.

That's why I always think that $1MM = $1M * 1000000
