Decimal storage units
Drive manufacturers commonly use powers of 1000: 1 GB = 1,000 MB and 1 TB = 1,000 GB.
Binary units
Computing contexts may use powers of 1024. Strict IEC names are KiB, MiB and GiB, although software interfaces sometimes label binary values as KB, MB or GB.
Why displayed capacity differs
A storage device labeled using decimal units can appear smaller when software reports capacity using binary calculations. Formatting and system files can also use some space.
Use the Data Storage Converter to compare units.
Quick answer
Convert bytes, KB, MB, GB and TB using decimal or binary units. Use the values and units shown by the tool, review the result, and keep the original inputs available if you need to compare another scenario.
Practical checklist
- Confirm the units, dates, rates or source values before calculating.
- Use consistent units and avoid rounding intermediate values too early.
- Run a second scenario when you need to understand how one input changes the result.
- For regulated fees, taxes, provider rules or professional decisions, verify the current official rule before relying on the result.
