GB to Bytes
Converts gigabytes to bytes using both 1000 and 1024 and shows both answers exactly.
One gigabyte equals 1,000,000,000 bytes by the decimal rule and 1,073,741,824 bytes by the binary rule. The difference is over 7%, and it grows with every next gigabyte.
The size in bytes is listed in the disk properties next to the rounded one: it makes it easy to check which rule the program uses.
Formula
By 1000: bytes = GB × 1,000,000,000. By 1024: bytes = GB × 1,073,741,824.
