Data Storage Converter
Convert between bytes, KB, MB, GB, TB and other data units Free, browser-based, no sign-up required.
What is Data Storage Converter?
A data storage converter is a tool that translates values between different digital storage units. In computing, data size can be expressed in many units — from tiny bits to massive exabytes. This free online Data Storage Converter uses the binary standard (1 KB = 1,024 Bytes) and lets you convert any value to every supported unit simultaneously. Whether you are calculating disk space, estimating bandwidth, or sizing cloud storage, this tool gives you instant, accurate conversions entirely in your browser.
How to Use
1. Enter a numeric value in the input field. 2. Select the source unit from the dropdown (e.g. GB, TB). 3. Instantly see the equivalent value in all other data units displayed in the conversion table below.
How It Works
The converter first translates your input value into bits — the smallest unit of digital information. From there, it divides by the appropriate factor for each target unit. All units use binary (×1024) conversion: 1 KB = 1,024 Bytes, 1 MB = 1,024 KB (1,048,576 Bytes), 1 GB = 1,024 MB, and so on. All calculations happen client-side in your browser — no data is sent to any server.
Common Use Cases
- Calculating how many photos, videos, or files will fit on a storage device
- Estimating cloud storage costs by converting between units used by different providers
- Converting network bandwidth or transfer rate units for system administration
- Sizing database storage requirements during capacity planning
- Comparing file sizes reported by different operating systems
- Converting between bits and bytes for networking calculations (Mbps to MB/s)
Frequently Asked Questions
How many megabytes are in a gigabyte?▼
1 GB = 1,024 MB. This tool uses binary conversion where each unit is 1,024 times the previous one: 1 KB = 1,024 Bytes, 1 MB = 1,024 KB, 1 GB = 1,024 MB, 1 TB = 1,024 GB.
Why does my hard drive show less space than advertised?▼
Hard drive manufacturers use decimal units (1 GB = 1,000,000,000 bytes), while operating systems display storage using binary units (1 GB = 1,073,741,824 bytes). A '500 GB' drive contains 500,000,000,000 bytes, which is approximately 465.66 GB in binary — the number your OS will display.
Is my data safe when using this tool?▼
Yes, completely. All calculations happen directly in your browser using JavaScript. No data is ever sent to a server or stored anywhere.
What is the largest unit this tool supports?▼
The tool supports conversions up to Exabytes (EB). An exabyte equals roughly one billion gigabytes — large enough for virtually any practical calculation.
