Convert file sizes and storage values between common digital units.
Convert KB, MB, GB and TB values using 1024-based digital storage steps.
Enter values and calculate instantly.
Storage units can be decimal or binary depending on the device, operating system, or hosting provider. That is why a phone, cloud plan, and computer may show slightly different available space even when the advertised capacity looks similar.
For best results, keep the original inputs visible until the final answer is checked. If the calculation affects payment, planning, health, travel, study, or official records, confirm the assumptions and use the related calculator pages for supporting values. On Data Storage Converter, read this point in the context of time and date planning, because the same advice can mean something different when the inputs, units and final decision change.
This converter changes storage values between KB, MB, GB and TB using 1024-based steps. It helps compare file sizes, backups, storage drives and data limits.
Formula: 1 MB = 1024 KB, 1 GB = 1024 MB and 1 TB = 1024 GB.
For storage conversion, choose whether the value starts as KB, MB, GB or TB before comparing file sizes or drive capacity.
| KB | Small files and text assets. |
|---|---|
| MB | Photos, documents and medium files. |
| GB | Videos, apps and backups. |
| TB | Large drives and bulk storage. |
Some providers use decimal storage units. This page uses 1024-based conversion for practical file-size estimates.
This page is most useful for digital storage unit conversion. Start with values that match your real situation, then change one input at a time to understand what affects the result most.
Use the result for comparing file sizes, drive space, cloud storage and backup requirements. If the number will be used for an official, financial, technical or purchase decision, keep the input values with the result so the estimate can be checked later.
| Photos | Often measured in MB and can add up quickly. |
|---|---|
| Videos | Often measured in GB when quality is high. |
| Backups | May need GB or TB planning depending on device size. |
Storage conversion is useful when a file, drive or cloud plan uses a different unit from the one you need. For backups, leave extra free space because software, indexing and temporary files can use additional capacity.
| Situation | What to check |
|---|---|
| Phone backup | Photos and videos can quickly move from MB to GB. |
| External drive | Displayed capacity can differ from advertised capacity. |
Convert KB, MB, GB and TB values using 1024-based digital storage steps.
Storage searches often start with a simple question such as what comes after TB or how KB, MB, GB and TB fit together. The converter is useful after you know whether the value is being treated as decimal storage or binary-style computer storage.
For everyday use, remember the order: KB, MB, GB, TB, PB, EB, ZB and YB. A phone, hard drive or cloud plan may advertise decimal capacity, while an operating system may display a slightly different usable amount.
When comparing file size with internet speed, do not mix bytes and bits. MB is commonly megabytes, while Mbps means megabits per second.
Many computer storage calculations use binary-style 1024 steps.
Manufacturers and operating systems may use different unit conventions.
No. MB is storage size and Mbps is data transfer speed.
