Kilobytes to bytes Conversion
1 kilobytes (kB) is equal to 1000 bytes (B).
1 kB = 1000 B
or
1 B = 0.001 kB
Formula
To convert a digital storage from kilobytes (kB) to bytes (B), multiply the digital storage in kilobytes by 1000
d(B) = d(kB) × 1000
Examples:
Convert 1 kilobytes to bytes:
d(B) = 1kB × 1000 = 1000 B

Frequently asked questions
How do I convert kilobytes to bytes?
Multiply the value in kilobytes by 1000 to get the result in bytes. For example, 5 kB × 1000 = 5000 B.
How many bytes are in 1 kilobytes?
1 kilobytes (kB) is equal to 1000 bytes (B).
How do I convert bytes back to kilobytes?
Use the inverse operation: divide the value in bytes by 1000 to get the result in kilobytes.
How accurate is the kilobytes to bytes conversion?
The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
