Data Size Converter

What is Data Size Conversion?

Data sizes are measured in bytes, with multiples like kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). There are two common systems: decimal (base 10, where 1 KB = 1000 bytes) and binary (base 2, where 1 KiB = 1024 bytes). This tool supports both, allowing you to convert between any of these units accurately.

Understanding data sizes is essential for estimating storage requirements, bandwidth calculations, and comparing file sizes. This converter handles large numbers (up to petabytes) and provides results with up to 4 decimal places.

All calculations are performed client‑side; your data never leaves the browser.

How to Use

Step 1: Enter the numeric value you want to convert.
Step 2: Select the source unit (e.g., MB).
Step 3: Select the target unit (e.g., GB).
Step 4: If you want binary units (KiB, MiB, etc.), check the "Use binary units" box.
Step 5: Click "Convert" to see the result.
Step 6: Copy the result using the "Copy Result" button.

The tool uses the appropriate conversion factor (1000 for decimal, 1024 for binary).

Examples

1 GB (decimal) → MB: 1000 MB
1 GiB (binary) → MiB: 1024 MiB
500 MB → GB: 0.5 GB
2 TB → GB: 2000 GB (decimal) or 2048 GB (binary)

Who Uses Data Size Converters?

• IT Administrators – planning storage capacity.
• Web Developers – calculating bandwidth and file upload limits.
• Content Creators – estimating video/audio file sizes.
• Cloud Engineers – sizing storage buckets.
• Students – learning computer science fundamentals.

Pro Tips

• When working with network speeds, use decimal units (1 Mbps = 1,000,000 bits/s). For storage, many operating systems report binary units (1 GB = 1,073,741,824 bytes).
• Use the binary option for precise disk space calculations.
• Remember that 1 byte = 8 bits; this tool converts bytes, not bits. For bits, use a separate tool.
• Copy the result directly into your calculations or documentation.
