Data Storage

Enter your gigabyte (GB) value into the input field on UntangleTools Data Storage Converter, select GB as the source unit, and all outputs including megabytes (MB) appear instantly. For binary conversion (used by operating systems): 1 GB = 1,024 MB. For decimal (SI standard, used by hard drive manufacturers): 1 GB = 1,000 MB. Copy the MB result in one click.

In binary (base-2) the standard used by Windows, macOS, and Linux for file sizes 1 GB = 1,024 MB (technically 1 GiB = 1,024 MiB). In decimal (base-10, SI) the standard used by storage manufacturers and most cloud providers 1 GB = 1,000 MB. So 2 GB = 2,048 MB (binary) or 2,000 MB (decimal). The tool supports both modes.

Select TB as your source unit. The converter instantly shows: 1 TB = 1,024 GB (binary) or 1 TB = 1,000 GB (decimal), and 1 TB = 1,048,576 MB (binary) or 1 TB = 1,000,000 MB (decimal). For terabyte to megabyte (tb to mb) conversions, binary is typically correct for file-system planning; decimal is correct for matching manufacturer specs.

This tool converts across the full hierarchy: bits (b) → bytes (B) → kilobytes (KB) / kibibytes (KiB) → megabytes (MB) / mebibytes (MiB) → gigabytes (GB) / gibibytes (GiB) → terabytes (TB) / tebibytes (TiB) → petabytes (PB) / pebibytes (PiB) → exabytes (EB). Enter any value, select any unit, and all conversions appear simultaneously no repeated inputs needed.

Four steps: (1) Type or paste your number into the input field. (2) Select the source unit from the dropdown (bits, bytes, KB, MB, GB, TB, PB, or their IEC binary equivalents like KiB, MiB, GiB). (3) All output units update instantly no button to press. (4) Click the Copy icon next to any result to copy it to your clipboard for immediate use.

Yes. The tool fully supports IEC binary prefix units: kibibyte (KiB = 1,024 bytes), mebibyte (MiB = 1,048,576 bytes), gibibyte (GiB = 1,073,741,824 bytes), tebibyte (TiB), and pebibyte (PiB). These are the technically correct units for binary-based storage measurements and are distinct from the decimal KB, MB, GB used by manufacturers. Both sets are selectable from the unit dropdown.

Yes. Bits (b) and bytes (B) are both available as base units, and all their multiples megabits (Mb), megabytes (MB), gigabits (Gb), gigabytes (GB) are supported. 1 byte = 8 bits always. This is essential for networking calculations: internet speeds are in megabits per second (Mbps) while file sizes are in megabytes (MB). The tool handles both systems and their cross-conversion cleanly.

In binary: 2 GB = 2 × 1,024 = 2,048 MB. In decimal: 2 GB = 2 × 1,000 = 2,000 MB. For a 2 GB mobile data plan or file, your phone and OS will typically show it as 2,048 MB in binary. For matching what a storage card manufacturer quotes, use 2,000 MB (decimal). The difference is 48 MB small but significant in precise calculations.

Results are calculated using full JavaScript floating-point precision (64-bit IEEE 754), sufficient for any practical data storage conversion. The tool strictly separates decimal SI units (KB = 10³ bytes) from binary IEC units (KiB = 2¹⁰ bytes), so you get mathematically correct answers rather than the rounded approximations that conflate the two standards. For values up to exabyte (EB) scale, precision is maintained throughout.
