Byte to KB/MB/GB/TB Converter
Convert storage sizes across Bytes, Kilobytes, Megabytes, Gigabytes, and Terabytes (both 1000 and 1024 standards). Designed for software developers, electrical engineers, students, and computer architecture researchers requiring deterministic client-side accuracy.
Enter byte count to view across all metric and binary units.

Active DerivationWhat Is Byte to KB/MB/GB/TB Converter?
This tool converts digital storage capacity between bytes and higher orders of magnitude. It supports both SI decimal prefixes (1000^n: KB, MB, GB, TB) and IEC binary prefixes (1024^n: KiB, MiB, GiB, TiB).
How Does It Work?
Divides the byte count by powers of 1000 for standard drive manufacturer units, and by powers of 1024 (2^10, 2^20, 2^30, 2^40) for operating system RAM and filesystem units.

Step-by-Step Example
Important Rules & Edge Cases
- 1 KB = 1,000 Bytes (SI standard).
- 1 KiB = 1,024 Bytes (IEC binary standard).
- Hard drive manufacturers use decimal 1000; operating systems like Windows report binary 1024.
Practical Applications in Engineering
- Understanding why a purchased "1 TB" drive shows only ~931 GB in Windows.
- Sizing cloud storage buckets, databases, and memory caches (Redis, Memcached).
- Capacity planning for data centers and embedded flash storage.
Common Mistakes to Avoid
- Caution: Assuming 1 KB is always 1024 Bytes without considering the context (SI vs IEC).
- Caution: Forgetting that 1 TB equals 1,000,000,000,000 bytes in decimal.
Frequently Asked Questions
Why does my 500GB hard drive only show 465GB in Windows?
Drive manufacturers sell drives in decimal units (500 × 1000^3 = 500,000,000,000 bytes). Windows calculates capacity in binary gigabytes (500,000,000,000 / 1024^3 ≈ 465.66 GiB).
