Convert Gigabytes to Bytes

The Conversion Formula

To convert gigabytes to bytes, multiply the value by the conversion factor: 1 GB = 1000000000 B. For a worked example, suppose you need to convert 25 GB to bytes: 25 × 1000000000 = 25000000000 B. To convert in the opposite direction, divide by 1000000000, or equivalently multiply by 1.0000e-9.

About gigabytes

The Gigabyte (GB) is the unit of the modern era. Hard drives, SSDs, smartphone storage, and monthly data plans are all measured in GB. The first 1 GB drive in 1980 was the size of a refrigerator; now 1 GB fits on a fingernail-sized card. gigabytes are commonly used in Phone storage (64/128 GB), RAM (8/16/32 GB), HD Movies, and Console games.

A 2-hour HD movie stream uses about 3-6 GB.

About bytes

The Byte (B) is the fundamental unit of digital storage. Historically, it was the number of bits needed to encode one character of text (8 bits). Everything from text files to 8K video is ultimately just a massive pile of Bytes. bytes are commonly used in File sizes, Disk capacity, RAM size, and Programming data types.

The word 'Hello' takes up 5 Bytes.

When Would You Convert gigabytes to bytes?

Converting between gigabytes and bytes is one of the most common digital storage conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 GB = 1000000000 B) memorized or bookmarked can save time in professional and everyday contexts alike.
