The International System of Units (SI) specifies a set of unit prefixes known as SI prefixes or metric prefixes.

exa- E 10^18 * 260
zetta- Z 10^21 * 270
yotta- Y 10^24 * 280
* Not generally used to express data speed
** k = 103 and K = 210
So the answer is 4.4M

4.4*10^6=4,400,000
4,400,000= 4.4million or 4.4mega= 4.4M
4,400,000= 4.4million or 4.4mega= 4.4M
