How to Convert Storage Units
- 1
Enter a value
Type a number into the input field -- for example, 500. The tool accepts whole numbers and decimals, so you can convert precise values like 1.44 MB.
- 2
Select the source unit
Choose the unit you are converting from: Bytes, KB, MB, GB, TB, or PB. The dropdown covers every standard storage unit you will encounter.
- 3
Choose binary or decimal mode
Toggle between binary (1 KB = 1024 bytes, used by operating systems) and decimal (1 KB = 1000 bytes, used by drive manufacturers). This distinction matters -- a "500 GB" hard drive holds about 465 GiB in binary.

Read all conversions at once
The tool instantly displays your value converted to every other storage unit simultaneously. No need to run separate calculations for GB-to-TB and GB-to-MB.
Precise Storage Math Without the Headaches
Binary & Decimal Systems
Switch between base-1024 (binary/IEC) and base-1000 (decimal/SI) conversions. This eliminates the confusion between GiB and GB that causes so many "missing storage" complaints.
All Units at Once
See the result in Bytes, KB, MB, GB, TB, and PB simultaneously. Useful when you need to compare values across different scales without repeated calculations.
Real-Time Calculation
Results update as you type -- no need to press a button. Change the value or unit and every conversion refreshes instantly.
Visual Size Examples
Contextual comparisons help you understand what a number actually means. For example, 4.7 GB is roughly one DVD, and 25 GB is one Blu-ray disc.
Works Everywhere
Runs entirely in your browser with no installation. Use it on your phone at a store comparing hard drive prices or on your desktop planning server storage allocations.
Who Converts Storage Units and Why
Cloud infrastructure engineers size storage volumes, estimate S3 costs, and plan database disk allocations daily. When a vendor quotes prices in GB (decimal) but your operating system reports usage in GiB (binary), the 7% discrepancy on a multi-terabyte volume translates to real budget surprises. This tool makes the binary/decimal distinction explicit so your capacity planning is accurate.
Students and everyday users encounter storage conversions when buying phones, SD cards, or external drives. Understanding that a "128 GB" phone actually provides about 119 GiB of usable space (before the OS takes its share) helps set realistic expectations. The tool gives a fast, reliable way to do the math instead of guessing.
Backup administrators and data migration teams need to calculate whether their data will fit on the target media. Converting a 2.4 TB database backup to see it is roughly 2,400,000 MB helps when comparing against bandwidth limits quoted in Mbps or storage quotas listed in different units.
Frequently Asked Questions
Why does my 1 TB hard drive only show 931 GB in Windows?
Drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes) while Windows reports in binary (1 TiB = 1,099,511,627,776 bytes). Dividing the decimal byte count by 1024 three times gives you approximately 931 GiB. No storage is missing -- it is a unit labeling difference.
What is the difference between MB and MiB?
MB (megabyte) in the SI/decimal system equals exactly 1,000,000 bytes. MiB (mebibyte) in the IEC/binary system equals 1,048,576 bytes. The binary prefix was introduced to end the ambiguity, though many operating systems still label binary values as "MB."
Which system should I use for network bandwidth?
Network speeds are almost always quoted in decimal (base-1000) units. A 100 Mbps connection transfers 100,000,000 bits per second, or about 12.5 MB/s. Use the decimal mode in this tool when calculating download times or bandwidth costs.
How many photos or songs fit in 1 GB?
Roughly 250 high-quality smartphone photos (4 MB each) or about 200 MP3 songs (5 MB each) fit in 1 GB. RAW photos from a DSLR are much larger at 25-50 MB each, so 1 GB holds only 20-40 RAW files. The tool helps you scale these estimates to any storage size.
