How many bits are in a byte?

There are exactly 8 bits in 1 byte. This is the fundamental rule this converter is built on, so 1 KB (1000 bytes) equals 8000 bits.

Are the results accurate?

Yes. The converter uses the exact relationship 1 byte = 8 bits and decimal SI prefixes (1 kilobyte = 1000 bytes). Calculations are done in double-precision and shown to 6 decimal places.

Is my data sent anywhere?

No. The conversion is privacy-first and runs entirely in your browser — the value you type never leaves your device.

Bits to Bytes Converter

This free data-unit converter moves between bits, bytes, kilobits (kbit), kilobytes (KB), megabits (Mbit), megabytes (MB), gigabits (Gbit) and gigabytes (GB). The whole conversion rests on one fixed rule: 1 byte = 8 bits.

Network speeds are usually quoted in bits per second (Mbit/s) while file sizes are quoted in bytes (MB), which is why a “100 Mbit” connection downloads at roughly 12.5 MB/s. Type any value, choose its unit, and every other unit updates instantly. All calculations happen locally in your browser — nothing is sent anywhere.
