Free Data Storage Converter Calculator Online
6 units: B, KB, MB, GB, TB, PB
The Data Storage Converter converts between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes — the units you encounter when dealing with file sizes, storage capacity, RAM, and data transfer limits. It uses the binary standard (1 KB = 1,024 bytes) that operating systems use to report storage.
Frequently Asked Questions
About the Data Storage Converter
Data storage units follow a confusing two-track standard: operating systems and programming tools use binary prefixes where 1 KB = 1,024 bytes, while hard drive manufacturers and internet service providers use decimal prefixes where 1 KB = 1,000 bytes. This discrepancy is why a "1 TB" drive only shows about 931 GB in Windows Explorer.
This converter uses the binary standard (powers of 2) that reflects how operating systems actually measure and report storage — the number that matters when you're managing files, allocating disk space, or understanding RAM specifications. The six units covered — byte, kilobyte, megabyte, gigabyte, terabyte, and petabyte — span the practical range from individual files to enterprise data centres.

Example Calculation
How many GB is a 4,700 MB Blu-ray movie file?
📥 Inputs
- Input: 4,700 MB
- Target unit: GB (binary)
- Convention: 1 GB = 1,024 MB
🔢 Calculation Steps
- 14,700 MB ÷ 1,024 = 4.59 GB
- 2In decimal (1 GB = 1,000 MB): 4,700 ÷ 1,000 = 4.7 GB
- 3OS will report ~4.59 GB; drive manufacturer labels it ~4.7 GB
Limitations of this Calculator
- Results are based purely on the mathematical relationship of the inputs provided.
- Does not account for edge cases or extreme outlier values that fall outside standard formula constraints.
