Bit/byte converters translate between bits, bytes, and larger data units (KB, MB, GB, TB) using binary (1024) or decimal (1000) scales.
공식
Decimal: 1 kB = 1000 bytes (used for storage/marketing)
단계별 가이드
- 11 byte = 8 bits
- 2Binary: 1 KB = 1024 bytes, 1 MB = 1024 KB (used for RAM)
- 3Decimal: 1 kB = 1000 bytes (used for storage/marketing)
풀어진 예시
입력
1 GB file
결과
1000 MB (decimal) or 1024 MB (binary), 8 billion bits
Decimal more common in marketing
피해야 할 일반적인 실수
- ✕Confusing binary and decimal scales (can be 7-10% different)
- ✕Forgetting to multiply bits by 8 when converting to bytes
자주 묻는 질문
Why two definitions of GB?
Standards conflict: NIST recommends binary (1024), but storage manufacturers use decimal (1000) in marketing.
Why do downloaded files seem smaller than stated?
Marketing uses decimal (1000); your computer shows binary (1024). 1000 GB marketed = 931 GB shown.
