How to read this mathematics value: 10^9

Question

I have this value

N = 10^9 (9 in superscript)

How to read that in English? translating from my native language, I would say

Ten base of nine.

but is that really correct?

Ten to the power of nine. Ten raised to the ninth power. Ten to the ninth power. — TimR, Mar 01 '15 at 12:05

Formally it is

Ten to the power of nine

but more commonly:

Ten to the nine or Ten to the ninth

The use of Base 9 has a very different meaning.

Or, in this specific case, "one billion". – David Richerby Mar 01 '15 at 15:40
Or, if you're old-school British, a milliard. See http://en.wikipedia.org/wiki/1,000,000,000 – WhatRoughBeast Mar 02 '15 at 17:54
If you're as old school British as I am, the word would be Gillion. You don't hear that much nowadays. – Chenmunka Mar 02 '15 at 18:43
