there are exactly 1 million gb in 1 petabyte
There are exactly 1 million gigabytes in a petabyte.1 petabyte (PB) = 1,000,000 gigabyte (GB)There are similar units based on powers of two instead of powers of ten, but at these large sizes, they are very rarely used, if ever:1 pebibyte (PiB) = 1,048,576 gibibytes (GiB).
As far as I know, there is no Pentabyte, but Petabyte. A Petabyte is equal to 1 048 576, or 2^20 Gigabytes.
There are 1,000,000 GB in one PB. 1 = byte 1,000 = kilobyte 1,000,000 = megabyte (million) 1,000,000,000 = gigabyte (billion) 1,000,000,000,000 = terabyte (trillion) 1,000,000,000,000,000 = petabyte (quadrillion)
PB - Petabyte. Then EB - Exabyte.
20 terabytes is 20,480 gigabytes.
1000 terabytes or 1 petabyte.
1 petabyte ≈ 1000 terabytes ≈ 1,000,000 gigabytes
Petabyte. The endings are Greek. It is also one million Gigabytes in the USA. We count differently than the UK or the rest of the world, for some reason. Mega= 1 x 10(6) Giga= 1 X 10 (7) Terra= 1 x 10 (8) Peta= 1x 10 (9) http://en.wikipedia.org/wiki/Petabyte
1 petabyte = 1 048 576 gigabytes So, 1 048 576 gigabytes times sixteen is 16 777 216 gigabytes. Hope this helps.
1 terabyte (TB) = 1000 gigabyte (GB) 1 petabyte (PB) = 1000 terabyte 1 exabyte (EB) = 1000 petabyte 1 zettabyte (ZB) = 1000 exabyte 1 yottabyte (YB) = 1000 zettabyte
The next level after megabyte is gigabyte. Following gigabyte is terabyte, petabyte, exabyte, zettabyte, and yottabyte.
1000 Megabytes are in 1 gigabyte. As are 1000 bytes in a kilobyte and 1000 kilobytes in 1 megabyte. 1000 Gigabytes in 1 terabyte and 1000 terabytes in 1 petabyte.
