Data Storage Converter 2026 | Bytes ↔ KB ↔ MB ↔ GB ↔ TB ↔ PB ↔ EB ↔ ZB ↔ YB

A Data Size Converter helps you convert between digital storage units such as bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and larger sizes. It is useful for understanding file sizes, cloud storage plans, database sizes, and download limits. This tool supports both standard decimal units (KB/MB/GB) and binary units (KiB/MiB/GiB) for accurate conversions.

KB, MB, GB and TB represent increasing levels of data size. In decimal format: 1 KB = 1,000 bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB, and 1 TB = 1,000 GB. These are commonly used by storage manufacturers and internet service providers. However, computers often use binary units (KiB/MiB/GiB), which can cause confusion when comparing storage values.

KB/MB/GB are decimal units (base-10), while KiB/MiB/GiB are binary units (base-2). Example: 1 KB = 1,000 bytes, but 1 KiB = 1,024 bytes. Similarly, 1 MB = 1,000,000 bytes, while 1 MiB = 1,048,576 bytes. Brutally honest: this is the main reason why file sizes and device storage values often look inconsistent across platforms.

This happens because storage manufacturers advertise capacity using decimal units (1 TB = 1,000,000,000,000 bytes), while many operating systems display storage using binary interpretation (1 TiB = 1,099,511,627,776 bytes). When converted, 1 TB appears as about 0.91 TiB (~931 GiB). This is normal and does not mean the drive is defective.

In decimal units: 1 GB = 1,000,000,000 bytes. In binary units: 1 GiB = 1,073,741,824 bytes. Whether you should use GB or GiB depends on the context—network providers and storage brands usually use GB, while operating systems and technical tools may show GiB.

Both can be correct depending on the unit system. In decimal (SI), 1 MB = 1000 KB. In binary (computer memory style), 1 MiB = 1024 KiB. Brutally honest: many websites incorrectly mix these two systems, which creates confusion. A high-quality converter should clearly separate MB vs MiB.

Yes. A reliable data size converter should support both decimal (KB/MB/GB/TB) and binary (KiB/MiB/GiB/TiB) units. Binary units are especially important for accurate computing, RAM/storage calculations, and technical documentation.

A bit (b) is the smallest unit of digital data, while a byte (B) usually equals 8 bits. Internet speed is typically measured in bits per second (Mbps, Gbps), while file sizes are measured in bytes (MB, GB). This is why download speeds look smaller than expected if you confuse MB/s with Mbps.

Because internet speeds use bits per second (Mbps), while files are measured in bytes (MB). Since 1 byte = 8 bits, you can estimate: MB/s ≈ Mbps ÷ 8. Example: 100 Mbps internet speed ≈ 12.5 MB/s maximum theoretical download speed. Real speed is often lower due to network overhead and server limits.

To convert Mbps (megabits per second) to MB/s (megabytes per second), divide by 8. Example: 80 Mbps ≈ 10 MB/s. Brutally honest: most people think their internet is slow because they expect 80 Mbps to mean 80 MB/s — but those are different units.

Yes. This converter uses standard conversion factors based on internationally accepted decimal (SI) and binary (IEC) units. It is accurate for computing, cloud storage estimation, file size calculations, and network-related comparisons.

Use decimal units (KB/MB/GB/TB) for storage plans, internet providers, and marketing specifications. Use binary units (KiB/MiB/GiB/TiB) for operating systems, RAM/storage calculations, and technical accuracy. If you want clarity, always check whether the unit uses 1000 or 1024 as the base.
