How many gb is 29 MB

Since 1 gb (gigabyte) is equal to 1,000 mb (megabytes), 29 megabytes is considerably smaller than a gigabyte. One gigabyte is somewhat more than 34 times more than 29 megabytes.

Here's a handy table:

Computers work in "Base 2", or "Binary" mathematics. There are only two digits in binary, 0 (zero) and 1 (one). This corresponds to the two positions of a simple switch, i.e., "off" or zero, and "on" or one. Because of this, there are some differences in the way certain numeric values are expressed in binary and the decimal system most people are more familiar with.

Computers calculate units of information, or "bytes", in terms of powers of 2: i.e., 1 kilobyte is actually two times itself ten times: 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024 bytes. This is expressed mathematically as "two to the tenth power". Thus, one megabyte would be 2 to the 20th power, or 1,048,576 bytes, one gigabyte would be 2 to the 30th power, or 1,073,741,824 bytes, and one terabyte would be 2 to the 40th power, or 1,099,511,627,776 bytes.

Note that hard drive manufacturers rate the capacity of their drives in Base Ten values: i.e., one gigabyte is calculated as 1,000,000,000 bytes, rather than the Base 2 value of 1,073,741,824 bytes.

This explains the discrepancy of the drive's rated capacity and the reported capacity in Windows' "My Computer". If you have a hard drive that has been rated by the manufacturer at, for instance, 40 megabytes, the value shown for the drive's capacity in "My Computer" will be 37.1 megabytes. You're not being cheated of capacity: it's just showing the same capacity in two differing measuring systems.
