Then why bastardise an SI prefix? This surely serves only to confuse
people. Why don't we invent a new word? Should we call it the
It is simply a convenient accident that 2^10 ~= 10^3. As I'm sure you're
well aware, this approximation starts to become way off as you approach
tera-. In fact, that's about 10% error, which is simply unacceptable.
It's time to move on and accept that the approximation fails with big
