Data storage converter

Convert bits, bytes, decimal storage units, and binary storage units.

What this calculator covers

Use this converter when you need to move between decimal storage labels such as GB and binary labels such as GiB without losing track of which unit system is being used.

The normalization step runs through bytes so the decimal-versus-binary difference stays explicit instead of being hidden behind a rounded label.

Frequently asked questions

What is the difference between GB and GiB?
GB (gigabyte) uses powers of 1,000, so 1 GB equals exactly 1,000,000,000 bytes. GiB (gibibyte) uses powers of 1,024, so 1 GiB equals 1,073,741,824 bytes. Hard drive manufacturers typically advertise in GB while operating systems often report capacity in GiB, which is why a drive can appear smaller than its labeled size.
Why does 1 GiB convert to more than 1,000 MB?
Because GiB is binary (base-1024) while MB is decimal (base-1000). One GiB holds 1,073,741,824 bytes, and dividing by 1,000,000 gives approximately 1,073.74 MB.
Can I convert bits directly?
Yes. Select "Bits" as the source unit. The converter treats 8 bits as one byte and uses that as the base for all other unit conversions.
What is the largest unit this converter supports?
The converter supports up to petabytes (PB) on the decimal side and tebibytes (TiB) on the binary side.

Primary result

1,073.741824 MB (Megabytes (decimal))

1 GiB converts to 1,073.741824 MB using bytes as the shared base unit.

Input
1 GiB (Gibibytes (binary))
bytes value
1,073,741,824 B
Converted value
1,073.741824 MB (Megabytes (decimal))
Exact factor
1,073.741824 MB per GiB

Step-by-step solution

  1. 1.Start with 1 GiB in Gibibytes (binary).
  2. 2.Normalize it to bytes: 1 x 1,073,741,824 = 1,073,741,824 B.
  3. 3.Convert the bytes value into Megabytes (decimal): 1,073,741,824 / 1,000,000 = 1,073.741824 MB.

Walkthrough

Visual walkthrough

data storage conversions normalize the source value into one shared base unit before expressing that same quantity in the target unit.

  1. 01

    Read the source data storage

    The calculator starts from 1 GiB in Gibibytes (binary).

    1 GiB

  2. 02

    Normalize to bytes

    1 x 1,073,741,824 = 1,073,741,824 B

    Using bytes as the common base keeps every supported data storage on one exact path.

  3. 03

    Express the result in Megabytes (decimal)

    1,073,741,824 / 1,000,000 = 1,073.741824 MB

    Re-expressing the base-unit value yields the requested Megabytes (decimal) result.
