Data Storage Converter - Free Online Data Size Converter

How to Use the Data Storage Converter

1. Enter a value — type the numeric data size you want to convert (e.g., 500, 2048, 0.5)
2. Select the source unit — choose the unit you’re converting from: B, KB, MB, GB, TB, or PB
3. Select the target unit — choose the unit you want to convert to
4. View the result — the converted value appears instantly as you type
5. Swap units — click the swap button to reverse the conversion direction

Perfect for IT, cloud storage planning, file size comparisons, and digital media.

Features

• 10+ storage units — covers Byte through Petabyte (B, KB, MB, GB, TB, PB)
• Binary (base-2) & decimal (base-10) — toggle between both standards for accurate conversions
• Real-time results — updates as you type without page reloads
• Two-way swapping — one click reverses source and target units
• Decimal support — enter fractional values like 1.5 GB
• No data sent — everything runs locally in your browser
• Clear display — shows the conversion formula alongside the result

Use Cases

• Cloud storage planning — convert your 500 GB free tier to MB to compare across providers who use different units
• File size calculations — a video is 4.7 GB but your USB has 8,000 MB free — quickly check if it fits
• Bandwidth monitoring — your internet plan is 200 Mbps, convert 50 GB download to understand transfer time
• Programming — convert between bytes and human-readable units for UI display or storage logic in code
• Hardware comparison — RAM (16 GB) vs SSD (512 GB) — convert to the same unit for a side-by-side comparison

FAQ

What’s the difference between binary (GiB) and decimal (GB)?

Decimal (base-10) uses powers of 1000: 1 GB = 1,000 MB. Binary (base-2 or GiB) uses powers of 1024: 1 GiB = 1,024 MiB. Hard drive manufacturers use decimal, while operating systems (Windows, macOS) typically report in binary. This is why a “500 GB” drive shows as ~465 GB on your computer.

Which unit should I use for cloud storage pricing?

Cloud providers (AWS, Google Cloud, Azure) bill using decimal (base-10) units. However, they often measure network transfer in bytes and storage in GB-months. Always check the fine print to confirm which standard they use.

How many MB are in a GB?

1 GB = 1,000 MB (decimal) or 1,024 MB (binary). Most consumer contexts (internet plans, phone storage) use decimal, while software and operating systems use binary.

What about bits vs bytes?

Bits (b) are 1/8 the size of bytes (B). Internet speeds are typically measured in bits per second (Mbps), while file sizes are in bytes (MB, GB). To convert: 100 Mbps ÷ 8 = 12.5 MB/s actual download speed.

What comes after terabyte?

Petabyte (PB), then exabyte (EB), zettabyte (ZB), and yottabyte (YB). This converter supports up to petabyte (PB), which covers most practical storage needs.
