Kilobytes to Bits (KB to bit) Converter
1 kilobyte equals 8,000 bits — multiply kilobytes by 8,000 to convert KB to bits. A kilobyte is 1,000 bytes (decimal SI definition) and each byte holds 8 bits, so 1,000 × 8 = 8,000 bits per kilobyte.
The formula
To convert kilobytes to bits, multiply by the exact factor:
bit = KB × 8,000
For example, 4 KB × 8,000 = 32,000 bits. The factor combines 1,000 bytes per KB and 8 bits per byte.

Where this conversion is used
Bits are the natural unit for network speed and transmission rates, while storage is measured in bytes and kilobytes. Converting KB to bits is common when you calculate how long a file will take to download over a connection quoted in megabits per second, or when you reason about protocol overhead and bandwidth at the bit level.
FAQ
How many bits are in a kilobyte?
One kilobyte equals 8,000 bits, using the decimal (SI) definition of 1,000 bytes per kilobyte.
Is 1 KB equal to 8,000 bits?
Yes. 1 KB = 1,000 bytes and each byte is 8 bits, so 1 KB = 8,000 bits.
How do I convert bits back to kilobytes?
Divide the bit value by 8,000 (or multiply by 0.000125). For example, 80,000 bits = 10 KB.
Is the conversion exact?
Yes, with the decimal definition of the kilobyte. If you use the binary definition (1 KiB = 1,024 bytes), a kibibyte would be 8,192 bits instead.
