From a single bit to the entire internet.
Understanding digital data sizes

Journey through the scales of digital information, from the smallest bit that powers your device to the vast yottabytes that could contain all human knowledge.

1 Bit (On or Off)
1024 Bytes in a Kilobyte
1,000,000,000,000,000,000,000,000 Bytes in a Yottabyte

Bit

Size: 1 bit
Symbol: b
In Bytes: 0.125 bytes

The smallest unit of data in computing. A bit can store a single binary value: either 0 (off) or 1 (on). Think of it as a light switch.

Real-world analogy:

If data were words, a bit would be a single letter's worth of information - just yes or no, on or off.

What can you store with this?

Did you know?

Internet Traffic

Global internet traffic reaches over 4.5 zettabytes per year - that's enough to store every movie ever made, thousands of times over.

DNA Storage

Scientists can store data in DNA at a density of about 1 exabyte per cubic millimeter - nature's ultimate storage solution!

Human Brain

Your brain can store an estimated 2.5 petabytes of information - equivalent to about 3 million hours of TV shows.
