Formula

1 KB = 1024 B | 1 MB = 1024 KB | 1 GB = 1024 MB | 1 TB = 1024 GB

Binary prefixes use powers of 1024 (2¹⁰), the convention used by operating systems and file managers. Each step multiplies or divides by 1024. Manufacturers and cloud providers instead use decimal (1000-based) prefixes, which is why advertised and displayed capacities differ by roughly 7 percent at the gigabyte scale and more at larger scales.

Worked Examples

Example 1: Photo Library Backup

Problem:A photo library is 5 GB (binary). Convert this to MB and KB to estimate cloud upload requirements.

Solution:MB = 5 GB x 1024 MB/GB = 5,120 MB\nKB = 5,120 MB x 1024 KB/MB = 5,242,880 KB\nBytes = 5,242,880 KB x 1024 = 5,368,709,120 bytes

Result:5 GB = 5,120 MB = 5,242,880 KB

Example 2: Video File Download Time

Problem:A video file is 2.5 GB. On a connection that transfers 12.5 MB/s (100 Mbps), how long will it take to download?

Solution:File size in MB = 2.5 GB x 1024 = 2,560 MB\nTime = 2,560 MB / 12.5 MB/s = 204.8 seconds\n204.8 / 60 = approximately 3.41 minutes

Result:2.5 GB at 100 Mbps takes approximately 3.4 minutes
