Enter a value, choose the unit you are converting from and the unit you want, and get the converted result instantly. It is useful for checking file sizes, storage capacity, memory, downloads, backups, and everyday computer and technology calculations.
How to Use the Data Storage Converter
The Data Storage Converter is easy to use. Enter the amount of data, choose the original unit, select the unit you want to convert to, and click Convert.
- Enter a data size.
- Select the unit under From.
- Select the unit under To.
- Click Convert.
- The converted value will appear instantly.
For example, enter 1024, select Kilobyte (KB) as the From unit and Megabyte (MB) as the To unit.
The result will be:
1024 KB = 1 MB
You can also enter decimal values such as 1.5 GB or 2.75 MB.
What Is Data Storage?
Data storage refers to the amount of digital information that can be stored on a device or storage system.
Photos, videos, documents, apps, games, music, and other files all use storage space.
Storage capacity is commonly expressed using units such as bytes, kilobytes, megabytes, gigabytes, and terabytes.
Common Data Storage Units
The converter supports:
- Bit (bit)
- Byte (B)
- Kilobyte (KB)
- Megabyte (MB)
- Gigabyte (GB)
- Terabyte (TB)
- Petabyte (PB)
- Exabyte (EB)
Each unit represents a different amount of digital data.
Bits and Bytes
A bit is one of the smallest units of digital information. It can have a value of either 0 or 1.
A byte contains 8 bits.
1 Byte = 8 bits
Bytes are commonly used when describing file sizes and storage capacity, while bits are also frequently used when discussing data transfer speeds.
Kilobytes
A kilobyte is larger than a byte.
This converter uses the binary convention:
1 KB = 1,024 bytes
Small text files, configuration files, and other lightweight digital files may be measured in kilobytes.
Megabytes
A megabyte is commonly used for larger files such as photos, songs, documents, and some applications.
Using the binary conversion:
1 MB = 1,024 KB
and:
1 MB = 1,048,576 bytes
For example:
5 MB = 5,120 KB
Gigabytes
Gigabytes are commonly used for phone storage, computer storage, memory cards, applications, games, and larger files.
Using the binary convention:
1 GB = 1,024 MB
For example:
2 GB = 2,048 MB
A smartphone advertised with 128 GB of storage has considerably more storage capacity than one with 64 GB.
Terabytes
A terabyte is a much larger storage unit.
Using the binary conversion:
1 TB = 1,024 GB
Terabytes are commonly associated with computer hard drives, SSDs, external drives, network storage, and backup systems.
For example:
2 TB = 2,048 GB
Petabytes
A petabyte is much larger than a terabyte.
1 PB = 1,024 TB
Petabytes are generally used when describing very large amounts of data, such as information stored by large organizations, cloud services, research systems, and data centers.
Exabytes
An exabyte is an extremely large data storage unit.
1 EB = 1,024 PB
Exabytes are generally used when discussing very large-scale digital data rather than everyday device storage.
Common Data Storage Conversions
Here are some useful conversions based on the binary system used by this converter:
| Data Unit | Equivalent |
|---|---|
| 1 Byte | 8 bits |
| 1 KB | 1,024 bytes |
| 1 MB | 1,024 KB |
| 1 GB | 1,024 MB |
| 1 TB | 1,024 GB |
| 1 PB | 1,024 TB |
| 1 EB | 1,024 PB |
KB to MB
To convert kilobytes to megabytes, divide the number of kilobytes by 1,024.
For example:
2,048 KB = 2 MB
This can be useful when checking file sizes or comparing storage requirements.
MB to GB
To convert megabytes to gigabytes, divide the number of megabytes by 1,024.
For example:
5,120 MB = 5 GB
This can help when working with large downloads, applications, videos, or storage capacity.
GB to TB
To convert gigabytes to terabytes, divide by 1,024.
For example:
2,048 GB = 2 TB
This conversion is useful when comparing hard drives, SSDs, backup storage, and other large-capacity devices.
File Size and Storage Capacity
File sizes and storage capacity are often described using the same basic units, but they refer to different things.
A file size tells you how much space a particular file uses.
Storage capacity tells you how much data a device can hold.
For example, a video might take up several gigabytes, while a phone or computer may have hundreds of gigabytes of total storage.
Why Does Available Storage Look Smaller?
You may notice that a storage device advertised with a particular capacity does not show exactly the same number in your operating system.
One reason is that manufacturers and operating systems can use different conventions for representing storage units.
The operating system may also use some space for system files, formatting, recovery partitions, or other data.
Because of this, the usable storage shown on a device can be lower than its advertised capacity.
Binary vs Decimal Storage Units
There are two commonly encountered ways of describing digital storage.
The binary system uses powers of 1,024:
1 KB = 1,024 bytes
The decimal system uses powers of 1,000:
1 kB = 1,000 bytes
Storage manufacturers commonly use decimal measurements when advertising drive capacities, while operating systems and software may use binary-based calculations or different labels.
This converter uses the binary convention, where each unit is 1,024 times the previous unit.
Data Storage for Phones
Phone storage is commonly listed in gigabytes.
For example, a smartphone might have:
- 64 GB
- 128 GB
- 256 GB
- 512 GB
- 1 TB
The actual amount of free space available can be lower because the operating system and pre-installed software also use storage.
Data Storage for Computers
Computers commonly use SSDs or hard drives with capacities ranging from hundreds of gigabytes to several terabytes.
A data storage converter can help when comparing storage capacities or estimating how much space is required for files, applications, games, photos, videos, and backups.
Data Storage for Cloud Backups
Cloud storage services also use units such as gigabytes and terabytes.
For example, if your files take up 750 GB, you can convert that amount into other units to better understand the total storage requirement.
This can be helpful when choosing a backup plan or checking how much space your files occupy.
Data Storage for Downloads
Large downloads are often shown in MB or GB.
For example, a 2.5 GB download is equivalent to:
2,560 MB
using the binary conversion used by this converter.
This makes it easier to compare download sizes with available storage space.
Data Storage vs Data Transfer Speed
Storage capacity and internet speed are related to digital data but measure different things.
Storage is commonly measured in bytes, such as:
GB or TB
Internet and network speeds are commonly expressed in bits per second, such as:
Mbps or Gbps
A GB and a Gb are not the same.
The capital B represents bytes, while the lowercase b represents bits.
Since:
1 Byte = 8 bits
a value expressed in gigabytes cannot be directly treated as the same value in gigabits.
Frequently Asked Questions
How many bits are in one byte?
1 Byte = 8 bits.
How many bytes are in one kilobyte?
This converter uses the binary convention:
1 KB = 1,024 bytes.
How many megabytes are in one gigabyte?
1 GB = 1,024 MB using the binary convention.
How many gigabytes are in one terabyte?
1 TB = 1,024 GB using the binary convention.

Yes. You can enter values such as 1.5 GB, 2.75 MB, or 0.5 TB.
Does the converter support terabytes?
Yes. You can convert between bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, and exabytes.
Does this converter use 1,000 or 1,024?
This converter uses 1,024 for each step between byte-based units.
What is the difference between bit and byte?
A byte contains eight bits:
1 Byte = 8 bits
Bits are commonly used for data transfer speeds, while bytes are commonly used for file sizes and storage capacity.
Can I convert GB to MB?
Yes. Select Gigabyte (GB) under From and Megabyte (MB) under To.
For example:
1 GB = 1,024 MB
Can I convert TB to GB?
Yes.
1 TB = 1,024 GB
Is a GB the same as a Gb?
No. GB means gigabyte, while Gb means gigabit.
A byte contains eight bits, so these units represent different amounts of data.
