Quickly convert between MB, GB and TB (decimal & binary)
Convert storage units precisely for planning, reporting or shopping. Supports both decimal (1 GB = 1000 MB) and binary (1 GiB = 1024 MiB) conventions.
Definition
A data storage converter calculates equivalent values between megabytes (MB), gigabytes (GB) and terabytes (TB).
Use decimal (SI) or binary (IEC) definitions depending on context:
decimal: 1 GB = 1,000 MB; binary (GiB, MiB): 1 GiB = 1,024 MiB.
Key Features
- Convert single values or multi-line lists (one value per line)
- Decimal (1000) and Binary (1024) modes
- Choose output precision and formatted numbers
- Copy results, clear input, and error validation
- Accessible, responsive layout for desktop & mobile
How to Use
- Enter a numeric value or paste multiple values (one per line) into the input area.
- Select the source unit (MB/GB/TB) and the target unit.
- Choose conversion mode: Decimal (1000) or Binary (1024).
- Pick decimal places for result formatting and click Convert.
- Use Copy to copy output or Clear to reset.
Real-World Use Cases
- Estimate download/upload times from file sizes and connection specs.
- Compare cloud storage plans (GB vs TB pricing).
- Prepare storage reports or capacity planning documentation.
- Convert file sizes exported from different operating systems (binary vs decimal).
Benefits
Save time by converting accurately and consistently. Avoid confusion between decimal and binary definitions, present neat formatted numbers in reports, and reduce errors when choosing storage plans.
FAQ
- 1. Which mode should I use—decimal or binary?
- Use decimal (1000) for disk vendor specifications and marketing; use binary (1024) for operating system file sizes and technical capacity planning.
- 2. Can I paste multiple values at once?
- Yes — paste values one per line. The tool will convert each line and output a matching list.
- 3. Will results include thousand separators?
- Yes — results are formatted with locale-aware separators for readability (e.g., 1,024.00).
- 4. Does the tool accept units in the input?
- The tool accepts plain numbers or numbers with unit suffixes (e.g., “500 MB” or “1.5 TB”). Unit suffixes are optional and parsed if present.
- 5. Is MB vs MiB distinguished here?
- This converter shows MB/GB/TB but lets you choose binary mode to emulate MiB/GiB/TiB behavior (1,024 base). For strict IEC notation (MiB/GiB/TiB) please note labels manually when using results.
