Data Storage Converter
Convert between data storage units
About the Calculator
Data sizes are listed in many units, which makes quick conversion important. This converter helps you move between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes using the standard 1024 based steps. Use it when a file size is shown in MB but a storage plan is listed in GB, or when you are planning backups and need consistent units. Enter a value, choose the from and to units, and get an accurate result instantly. It is a simple way to avoid mistakes when comparing drives, cloud tiers, or download sizes. Clear units make storage decisions much easier. Use the Data Storage Converter to get a clear result you can act on right away.

Examples
Convert 2 gigabytes to megabytes
2 GB = 2,048 MB
Convert 500 megabytes to gigabytes
500 MB = 0.488 GB
Convert 1 terabyte to gigabytes
1 TB = 1,024 GB
Tips & Strategies
This converter uses binary steps where 1 KB = 1. 024 bytes.
Quick tip. File sizes shown in MB may be smaller or larger depending on the system used.
Quick tip. Use consistent units when comparing storage plans or backup requirements.
Cross-check when the decision matters. Run a second scenario with rounded inputs or a different path to the same quantity so you do not rely on a single fragile chain of arithmetic.
Write down units and rounding rules next to the answer. Half of spreadsheet mistakes are inconsistent units or silent rounding; noting assumptions makes the number usable a month later.
Things Worth Knowing
- •The kilobyte confusion: hard drive manufacturers use 1 KB = 1,000 bytes (decimal) but operating systems use 1 KB = 1,024 bytes (binary), meaning a "500 GB" hard drive only shows as 465 GB in Windows; you did not lose 35 GB, it is just different math.
- •The human brain's storage capacity: the human brain can store approximately 2.5 petabytes (2,500 terabytes) of information, enough to hold 3 million hours of TV shows, though unlike computers we cannot choose what we remember or forget.
- •Smartphone storage evolution: the first iPhone (2007) had 4-16 GB of storage; today's phones have up to 1 TB, a 62x increase in just 19 years, while a 1 TB phone holds more data than a $20 million IBM mainframe from 1980.
- •The floppy disk to modern ratio: a 1.44 MB floppy disk (1987) would need 694,445 disks to equal a single 1 TB drive; if stacked, that would be a 229-foot tall tower (22-story building) of floppy disks.
- •Global data creation: humanity creates approximately 328.77 million terabytes (330 exabytes) of data every day as of 2026, the equivalent of 100 billion DVDs daily or watching every movie ever made 50,000 times over.
