Bytes to Bits converter (B to bits)
Convert Bytes (B) to Bits (bits) with this free calculator. Type a value, press Convert, and the page applies the same factor shown in the formula below — no rounded shortcut, and nothing is stored on a server.
How to convert Bytes to Bits
1 byte (B) is equal to 8 bits.
Bits = Bytes × 8
Multiply the bytes by 8:
Example: Convert 4 bytes to bits:
Bits = 4 × 8 = 32 bits

How this calculator works
The form on this page is a Bytes-to-Bits converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the bits result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
