Digital storage units are used to measure data capacity in computing and digital systems. The basic unit is a byte, which represents 8 bits of data. As data sizes grow larger, we use larger units like kilobytes (KB), megabytes (MB), and gigabytes (GB).
| Unit | Equivalent in Bytes | Scientific Notation |
|---|---|---|
| 1 Kilobyte (KB) | 1,024 bytes | 2¹⁰ bytes |
| 1 Megabyte (MB) | 1,048,576 bytes | 2²⁰ bytes |
| 1 Gigabyte (GB) | 1,073,741,824 bytes | 2³⁰ bytes |
| 1 Terabyte (TB) | 1,099,511,627,776 bytes | 2⁴⁰ bytes |
To convert bytes to gigabytes, divide the number of bytes by 1,073,741,824 (1024³). This is because:
Let's convert 5,368,709,120 bytes to GB:
5,368,709,120 ÷ 1,073,741,824 = 5 GB
Understanding bytes to GB conversion is crucial when:
