No button, no wait. The worked answer is already on the page before any script runs.
Tebibyte and Byte
A tebibyte is 1,024 gibibytes. The gap against the terabyte has grown with each step: 2.4% at kilo, 4.9% at mega, 7.4% at giga, 10% at tera.
A byte is eight bits, though that was not always fixed — early machines used six, seven or nine. The eight-bit byte won because it holds one character of text and divides neatly in half.

Convert TiB to B: common questions
How many bytes are in a tebibyte?
Exactly 1099511627780. One tebibyte is 1099511627780 bytes, and the box above will do it for any figure you type.
Is this conversion exact, or rounded?
The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.
Why does another converter show a slightly different number?
Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
Where these figures come from
The claims this page makes about data units are checkable, and these are the documents that settle them.
How this page works
The factor is a constant in the page and the arithmetic is four operations, so nothing is sent anywhere and nothing needs to be. The number you type never leaves the browser — there is no request for it to travel in.
