DATA STORAGE CONVERSION
Bit to Byte.
Convert bit (b) to byte (B), with the math explained.
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 bit to byte
Multiply your bit value by 0.125 to get the equivalent in byte. Both units are normalized through the byte.
B = b × 0.12510 b = 1.25 B
Result rounded to 12 significant digits. Change the precision in the calculator to suit your task.1 kB = 1,000 bytes; 1 KiB = 1,024 bytes. Lowercase b means bit; uppercase B means byte.
