Data Storage Converter - Byte, KB, MB, GB, TB

Convert digital data storage units between Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, and Petabyte. Uses both binary (1024-based) and decimal (1000-based) standards. Essential for IT professionals, data scientists, and anyone working with file sizes and storage capacity.

Data Storage Conversion Factors

1 GB = 1000 MB = 1,000,000 KB = 10⁹ Byte

Variables:

  • 1 Byte8 bits
    8 bits(e.g.: = 1 text character)
  • 1 KBKilobyte (decimal)
    Kilobyte (decimal)(e.g.: = 1000 Byte)
  • 1 KiBKibibyte (binary)
    Kibibyte (binary)(e.g.: = 1024 Byte)
  • 1 MBMegabyte
    Megabyte(e.g.: = 1000 KB = 10⁶ Byte)
  • 1 GBGigabyte
    Gigabyte(e.g.: = 1000 MB = 10⁹ Byte)
  • 1 TBTerabyte
    Terabyte(e.g.: = 1000 GB = 10¹² Byte)

How to Use the Data Storage Converter

  1. 1

    Enter Size

    Input the data size value.

  2. 2

    Select Unit

    Choose Byte, KB, MB, GB, TB, PB, or binary units.

  3. 3

    Select System

    Choose decimal (1 KB = 1000 B) or binary (1 KiB = 1024 B).

Examples

MB to GB

Problem:

Convert 1500 MB to GB (decimal)

Solution:
  1. 1.1500 ÷ 1000 = 1.5
Result:1.5 GB

1500 MB equals 1.5 GB in decimal notation.

GiB to GB

Problem:

OS shows 256 GiB. How many GB decimal?

Solution:
  1. 1.256 × 1024 ÷ 1000 ≈ 262
Result:~262 GB

Binary vs decimal explains capacity differences.

Frequently Asked Questions

What is the difference between KB and KiB?
KB (kilobyte) = 1000 bytes (SI decimal). KiB (kibibyte) = 1024 bytes (IEC binary). Storage makers often use decimal; operating systems often use binary—causing apparent 'missing' capacity.
How many GB in 1 TB?
Decimal: 1 TB = 1000 GB. Binary: 1 TiB = 1024 GiB. RAM is usually binary; SSD/HDD labels are usually decimal.
Why is my HDD smaller than labeled?
Manufacturers use 1 GB = 10⁹ bytes; OS uses 1 GiB = 2³⁰ bytes. The gap is ~7% per GB and grows with capacity.
What comes after terabyte?
KB → MB → GB → TB → PB (petabyte) → EB → ZB → YB. Each step ×1000 (decimal) or ×1024 (binary).
