FAQ
What is the formula to convert bytes to GB?
Divide the number of bytes by 1,073,741,824 = 1,024 × 1,024 × 1,024 (2³⁰): GB = bytes ÷ 1,073,741,824. For example, 1,073,741,824 bytes = 1 GB, 4,294,967,296 bytes = 4 GB and 1,000,000,000 bytes ≈ 0.93 GB.
Why does a 500 GB drive show about 465 GB in Windows?
Because the box and Windows count on different scales. The manufacturer sells 500 GB as 500,000,000,000 bytes, in decimal (SI) units where 1 GB = 1,000,000,000 bytes; Windows divides the same bytes by 1,073,741,824 and shows about 465.66 GB, about 6.9% fewer. No space is missing, and this converter uses the binary scale of Windows.
How many bytes are in a gigabyte?
1,073,741,824 bytes on the binary scale of operating systems, RAM and this converter: 1 GB = 1,024 MB, 1 MB = 1,024 KB and 1 KB = 1,024 bytes. The IEC name for this unit is the gibibyte (GiB). On the decimal scale of drive vendors a gigabyte is exactly 1,000,000,000 bytes.
