Definition of kilobyte

  1. :  1024 bytes

Did You Know?

Knowing the root kilo-, you might think a kilobyte would be exactly 1,000 bytes. But actually a kilobyte represents the power of 2 that comes closest to 1,000: that is, 210 (2 to the 10th power), or 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2, or 1,024. Why 2? Because the capacity of memory chips is always based on powers of 2. Locations in electronic memory circuits are identified by binary numbers (numbers that use only the digits 0 and 1), so the number of addressable locations becomes a power of 2.

Origin and Etymology of kilobyte

from the fact that 1024 (210) is the power of 2 closest to 1000


First Known Use: 1970
