Free Data Storage Converter - KB, MB, GB, TB Conversion Online

A You're seeing bits versus bytes confusion. Internet speeds are advertised in megabits per second (Mbps), but file sizes show in megabytes (MB). One byte equals 8 bits, so 500 Mbps translates to roughly 62.5 MB/s before network overhead cuts it. Use our converter: type 500 in the megabit field, switch to binary mode, and read the megabyte output. That theoretical max explains the gap.

A No, the conversion is instant either way. Both modes process your input in under a second, even for petabytes. The only thing that changes is the math: decimal divides by 1000, binary divides by 1024. If you're converting a 10 TB drive to bytes, decimal mode gives you 10,000,000,000,000 bytes. Binary mode gives 10,995,116,277,760 bytes. Pick the mode first, then type your number.

A A kilobyte (KB) uses decimal and equals 1000 bytes. A kibibyte (KiB) uses binary and equals 1024 bytes. Most operating systems and RAM manufacturers report in binary, but hard drive makers use decimal. If you're buying a 1 TB external drive for backups, decimal mode tells you the advertised size. Switch to binary to see what your computer will actually display — roughly 931 GB. Our converter labels both modes clearly, so you're never guessing.

A Absolutely, and it handles it instantly. A petabyte equals 1,125,899,906,842,624 bytes in binary mode. That's a huge number, but our converter manages the math client-side without bogging down your browser. Type 1 in the petabyte field, select kilobytes, and the result appears in milliseconds. No server calls, no lag. I've tested it with 10 PB just to be sure.

A You'll get numbers that don't match reality. Say you convert 1 TB to MB using decimal mode, then try to compare that result against a file size listed in binary MB. Decimal says 1,000,000 MB, binary gives 1,048,576 MB. That's a 48 MB gap right there. Our tool does one conversion at a time, so you won't accidentally blend modes, but watch your selections when copying results into spreadsheets. Pick one mode and stick with it for any given project, or label columns clearly.

A You should definitely watch out for the manufacturer versus OS discrepancy. Drive makers list 1 TB as exactly 1,000,000,000,000 bytes, while Windows reports that same drive as roughly 931 GB. This isn't a scam or a broken drive, just a different way of counting bytes. Use our binary mode to see what your computer actually displays before transferring your data. Always check your operating system settings to see if it uses GiB or GB labels.

A That's not a defect, it's a unit mismatch. Manufacturers advertise 1TB as 1,000,000,000,000 bytes using decimal math. Windows, however, reports storage in binary, where 1TB equals 1,099,511,627,776 bytes. So your drive's actual decimal capacity divided by the binary terabyte value lands at roughly 931GiB. Punch 1 into the TB field here, switch to binary mode, and you'll see the exact number your OS displays. This confusion trips up everyone, not just new builders.

A Yes, just highlight the result and copy it like any other text on the page. There's no download button, but the output appears as plain numbers, so it pastes cleanly into Excel or Google Sheets without formatting issues. One tip: paste as values, not formulas, or your spreadsheet might try to reinterpret the number. For a 2 TB drive in decimal mode, you'll get 2,000,000,000,000 bytes, which Sheets sometimes auto-converts to scientific notation. Set the column format to plain text first if that bugs you.

A Phones bought from international stores often list storage in decimal gigabytes while your computer reads them in binary. A 512 GB phone might show up as roughly 476 GB on your screen. Plug 512 into our tool and flip to binary mode to see that exact number before you panic. It saves you from returning a perfectly fine device over a math quirk.

A No tool on the web touches your actual files. This converter only calculates numbers based on the digits you type into the input boxes. Type 500 into the gigabyte field and get 500,000 megabytes in decimal mode. Your hard drive never connects to our site. Feel free to copy paste values without worrying about file corruption.
