데이터 크기 변환기

디지털 데이터 크기 단위를 변환하세요 — 바이트, 킬로바이트, 메가바이트, 기가바이트, 테라바이트 및 이진 단위를 지원합니다.

디지털 저장 단위를 변환하세요 — 십진법(KB, MB, GB)과 이진법(KiB, MiB, GiB)

결과
변환할 값을 입력하세요
십진 단위(KB, MB, GB)는 1000 배수를, 이진 단위(KiB, MiB, GiB)는 1024 배수를 사용합니다. OS와 하드웨어는 크기를 다르게 표시할 수 있습니다.

How to Use This Tool

  1. 1

    Enter a data size value

    Type the numeric file or storage size you want to convert.

  2. 2

    Select the source unit

    Choose from bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, or their binary equivalents (KiB, MiB, GiB, TiB, PiB).

  3. 3

    Pick the target unit

    Select the unit to convert to. Use the swap button to quickly reverse the conversion direction.

  4. 4

    Compare all units at once

    The expanded table below the result shows your value in every data size unit — both decimal (SI) and binary (IEC) standards.

Frequently Asked Questions

What is the difference between MB and MiB?
MB (megabyte) uses the decimal standard: 1 MB = 1,000,000 bytes. MiB (mebibyte) uses the binary standard: 1 MiB = 1,048,576 bytes. Hard drive manufacturers use MB, while operating systems often use MiB.
How many gigabytes are in a terabyte?
In the decimal (SI) standard, 1 TB = 1,000 GB. In the binary (IEC) standard, 1 TiB = 1,024 GiB.
Why does my hard drive show less space than advertised?
Manufacturers label drives using decimal units (1 TB = 1,000 GB), but many operating systems display sizes in binary units (1 TiB = 1,024 GiB). This makes a 1 TB drive appear as roughly 931 GiB.
What are the binary IEC units?
IEC units (KiB, MiB, GiB, TiB, PiB) use powers of 1,024 instead of 1,000. They were introduced to eliminate confusion between decimal and binary interpretations of kilo, mega, giga, etc.
