Understanding Digital Storage Conversion

Digital storage conversion is essential when working with file sizes, storage devices, and data transfer. Computer systems use both decimal (base-10) and binary (base-2) systems, leading to two different conversion factors:

Decimal (SI) Standard

1 Gigabyte (GB) = 1000 Megabytes (MB)
Used by storage manufacturers and most software

Binary (IEC) Standard

1 Gibibyte (GiB) = 1024 Mebibytes (MiB)
Used by operating systems and memory measurement

Practical Examples

A 256GB SSD actually has 256,000,000,000 bytes of storage
Windows might show this as 238 Gibibytes (GiB)
A 100MB file equals 0.1GB in decimal or approximately 0.0931GiB in binary

Frequently Asked Questions

Why are there two different conversion standards?

Computer systems naturally work in binary (base-2) while the metric system uses decimal (base-10). This has led to two different standards being used in different contexts.

Which standard should I use?

Use decimal conversions when working with storage manufacturers and most applications. Use binary conversions when working with operating systems and memory measurements.

Why does my 1TB hard drive show less capacity?

Manufacturers use decimal measurements (1TB = 1,000GB) while operating systems use binary (1TiB = 1,024GiB), resulting in apparent "missing" space.
