One value, every size — bits, bytes, and decimal and binary kilo, mega, giga, tera, peta. A gigabyte means two things, depending on who's selling.
KB is 1,000 and KiB is 1,024 — the difference is why your 1 TB drive shows 931 GB.

pro tips
KB is 1,000 and KiB is 1,024 — the difference is why a 1 TB drive shows 931 GB. Now you can see both on the same screen.
A bit is the smallest unit, a byte is 8 bits, and a gigabyte is the size of your family's patience with your downloads.
Same number, two meanings: storage marketing says GB, your OS says GiB. That's not a bug, it's a decimal point with opinions.
what it does
Type a number, pick its unit, and every other size updates at the same time. Bits, bytes, and both the decimal and binary versions of kilo, mega, giga, tera and peta — the whole storage rack in one screen.
The conversion runs through bytes, the unit everyone quietly agrees on. Click any result to copy that particular value, because someone will always ask for the number in gigabytes.
Handy for downloads, storage, specs and the eternal "is that a lot of space?" — the question that haunts every family hard drive.
Use it when a file says MB but your plan says GB, when a spec sheet quotes gigabytes and the drive reports gibibytes, or when someone brags about a "1 terabyte drive" and you want to check the fine print. The two groups — decimal and binary — sit side by side so the difference finally makes sense.
quick answers
What's the difference between GB and GiB?
GB counts in thousands (1,000), GiB counts in binary (1,024). Same idea, different numbers — that's why a "1 TB" drive shows 931 GiB on your computer.
Why does my drive show less space than advertised?
Manufacturers quote decimal (1 TB = 1,000 GB); operating systems count binary (931 GiB). It's arithmetic, not a conspiracy.
How many MB are in a GB?
1,000 in decimal or 1,024 in binary — the widget shows both so you never have to pick a side in the comments section.
What's the difference between a bit and a byte?
A bit is one 0 or 1; a byte is 8 bits. Storage is measured in bytes, internet speeds are sold in bits — the eternal confusion.
