Convert byte (B) to kilobyte (kB), with the math explained.
1 B = 0.001 kB
1 kB = 1,000 bytes; 1 KiB = 1,024 bytes. Lowercase b means bit; uppercase B means byte.
THE MATH, MADE SIMPLE
How to convert byte to kilobyte
Multiply your byte value by 0.001 to get the equivalent in kilobyte. Both units are normalized through the byte.
kB = B × 0.00110 B = 0.01 kB
