Convert Bytes to Gigabytes
B to GB · digital storage conversion
What are bytes and gigabytes?
A byte is 8 bits, enough to store one character of text. A gigabyte is one billion bytes, about a quarter-hour of HD video. 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 bytes to gigabytes
1 B = 1.0000e-9 GB. To convert, multiply the number of bytes by 1.0000e-9. For example, 5 B = 5.0000e-9 GB, and 20 B = 2.0000e-8 GB. To go the other way, multiply gigabytes by 1,000,000,000 (since 1 GB = 1,000,000,000 B).
