Understanding Data Units

Data storage units can be confusing because there are two standards: Decimal (base 10) and Binary (base 2).
1. Megabytes (MB) to Gigabytes (GB)
In the decimal system (common for marketing storage media), 1 GB = 1000 MB. In the binary system (used by Windows), 1 GiB = 1024 MiB.
GB = MB / 1000
Example 1: Convert 5000 MB to GB
- Formula: 5000 / 1000
- Result: 5 GB
Example 2: Convert 2500 MB to GB
- Formula: 2500 / 1000
- Result: 2.5 GB
2. Terabytes to Gigabytes
1 Terabyte (TB) is equal to 1000 Gigabytes (GB).
GB = TB × 1000
Example 1: Convert 2 TB to GB
- Formula: 2 × 1000
- Result: 2000 GB
Example 2: Convert 0.5 TB to GB
- Formula: 0.5 × 1000
- Result: 500 GB
