About This Tool


Data size conversion is essential for understanding storage capacity and file sizes. Our converter handles all common units from bytes to petabytes.

The converter supports both binary (base-1024) and decimal (base-1000) calculations. Binary is traditional in computing (1 KB = 1024 bytes), while decimal is used for marketing storage capacities (1 KB = 1000 bytes).

Common conversions: 1 MB = 1024 KB (binary) or 1000 KB (decimal), 1 GB = 1024 MB, 1 TB = 1024 GB. The difference matters for large storage: a 1 TB drive has about 931 GB in binary terms.

This tool helps when comparing file sizes, planning storage needs, calculating bandwidth requirements, or understanding why your storage seems smaller than advertised.

Understanding both binary and decimal measurements helps avoid confusion when working with storage devices, cloud services, and file management.

Frequently Asked Questions

What's the difference between binary and decimal?
Binary uses 1024 (2^10) per unit, traditional in computing. Decimal uses 1000, common in marketing. A "1 TB" drive is actually ~931 GB in binary.
How many KB in 1 MB?
In binary: 1024 KB. In decimal: 1000 KB. Most operating systems use binary.
Why is my storage smaller than advertised?
Drives are marketed using decimal (1 TB = 1,000,000,000,000 bytes), but OS shows binary (1 TB = 1,099,511,627,776 bytes).
What about bits vs bytes?
One byte = 8 bits. Network speeds often use bits (Mbps), while storage uses bytes (MB).
What comes after TB?
Petabyte (PB), Exabyte (EB), Zettabyte (ZB), Yottabyte (YB). Each is 1024× the previous.
