Bytes to Kilobytes Converter
Convert file sizes, memory allocations, or bandwidth ceilings from bytes to binary kilobytes (KiB) using the exact 1 KiB = 1,024 bytes definition. Paste large numbers and receive a nicely formatted result for documentation or reporting.
Figures are informational. Verify unit conventions with your infrastructure or compliance requirements before publishing specs.
Examples
- 2,048 bytes ⇒ 2 KiB
- 1,048,576 bytes ⇒ 1,024 KiB
- 12,582,912 bytes ⇒ 12,288 KiB
FAQ
Is this calculator using binary or decimal kilobytes?
It uses binary units (1 KiB = 1,024 bytes). Many operating systems and programming languages rely on the binary definition for memory and storage calculations.
How do I convert to decimal kilobytes (kB)?
For decimal kB used by some networking equipment, divide bytes by 1,000 instead of 1,024. The Additional Information panel explains the difference.
Can I reverse the calculation?
Yes. Multiply kilobytes by 1,024 to return to bytes, or use our Kilobytes to Bytes calculator for automation.
Additional Information
- Binary prefixes: 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB, 1 GiB = 1,024 MiB.
- Decimal prefixes: 1 kB = 1,000 bytes. Storage manufacturers often advertise using decimal units.
- When planning API payload limits or CDN caching, round down results to avoid exceeding byte quotas.
- Use thousands separators when copying results into documentation for readability and fewer manual errors.
