Yottabytes (YB) to Gigabytes (GB) Converter
Convert yottabytes to gigabytes.
1 YB = 1,000,000,000,000,000 GB
How to convert YB to GB
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Yottabyte is 1024 bytes and 1 Gigabyte is 109 bytes. Divide one by the other and you get the ratio between the two units: 1024 ÷ 109 = 1015.
Yottabyte is the bigger unit, so you multiply. Every YB holds 1015 GB, which means the decimal point moves 15 places to the right.
On the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB) these two are 5 steps apart. Every step is a factor of 1,000, so 5 steps means 1,000 multiplied by itself 5 times, which is 1015.
The formula
GB = YB × 10151 YB = 1 × 1015 GB1015 means 1 followed by 15 zeros
Worked example 1: Converting 1 YB
1 YB × 1015 = 1 × 1015 GBThe decimal point moves 15 places to the right.
No storage system with published figures reaches a yottabyte yet.
Worked example 2: Converting 0.5 YB
0.5 YB × 1015 = 500,000,000,000,000 GBThe decimal point moves 15 places to the right.
Worked example 3: Converting 12.75 YB
12.75 YB × 1015 = 1.275 × 1016 GBThe decimal point moves 15 places to the right.

Where YB to GB comes up
A yottabyte is 1,000 zettabytes, which is 1024 bytes. Yottabytes are mostly a textbook and forecast unit. You meet them in articles about how large data totals could grow.
A gigabyte is 1,000 megabytes, about 250 photos at 4 MB each. Gigabytes are the language of phone storage, RAM, mobile data plans, game installs and USB sticks.
Going from yottabytes down to gigabytes always gives a bigger number, because the unit you land on is smaller. It is the usual direction when a limit or a form asks for a smaller unit than the one you have in mind.
YB to GB FAQ
How many gigabytes are in 1 yottabyte?
