On a computer 1GB = 1024MB, the hard drive manufacturer usually converts by 1GB = 1000MB. Take a 120GB hard drive as an example:
Vendor capacity calculation method: 120GB = 120,000MB = 120,000,000KB = 120,000,000,000 bytes
Convert to operating system. Calculation method: 120,000,000,000 bytes / 1024 = 117,187,500KB / 1024 = 114,440.9MB = 111.8GB.
The picture is for reference only, the hard drive is a second-hand teardown hard drive.
