Convert Gigabytes to Bits
GB to b · digital storage conversion
What are gigabytes and bits?
A gigabyte is one billion bytes, about a quarter-hour of HD video. A bit is the smallest unit of digital data, a single 0 or 1. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert gigabytes to bits
1 GB = 8,000,000,000 b. To convert, multiply the number of gigabytes by 8,000,000,000. For example, 5 GB = 40,000,000,000 b, and 20 GB = 160,000,000,000 b. To go the other way, multiply bits by 1.2500e-10 (since 1 b = 1.2500e-10 GB).

FAQ
What is 1 GB in b?
1 GB = 8,000,000,000 b. To convert any amount, multiply the number of gigabytes by 8,000,000,000.
How do I convert bits back to gigabytes?
Go the other way: 1 b = 1.2500e-10 GB, so multiply bits by 1.2500e-10 to get gigabytes.
Is a gigabyte bigger than a bit?
Yes — 1 GB is the larger unit, equal to 8,000,000,000 b.
