Data Storage Converter

Data Storage Converter

Convert between bits, bytes, decimal storage units, and binary IEC units. The table makes the difference between MB and MiB, GB and GiB, and TB and TiB visible instead of hiding it behind one result.

Formula

Data storage conversion formula

The converter normalizes every value into bits, then divides by the target unit factor. Decimal units use powers of 1000, while binary IEC units use powers of 1024.

Working formulas

Base conversion

bits = value x bits per source unit

Every source value is converted into bits first.

Target value

target value = bits / bits per target unit

The bit value is scaled into the selected target unit.

Decimal vs binary

1 MB = 10^6 B, but 1 MiB = 2^20 B

This is the common source of storage-size confusion.

Symbols

B - byte
Eight bits. Used as the base for most file-size labels.
MiB - mebibyte
A binary IEC unit equal to 1,048,576 bytes.
Why Users Love This Tool

Why decimal and binary labels matter

Prevents MB/MiB confusion

  • Decimal storage labels use powers of 1000, while binary IEC labels use powers of 1024.
  • The table shows both systems at once, which helps explain disk capacity and memory-size differences.
  • Bits and bytes stay visible so network-transfer and file-storage values can be compared carefully.

Useful for technical documentation

  • The conversion method is explicit enough for support tickets, specs, and storage planning notes.
  • Very large and very small values are formatted for readability.
  • The source system column helps readers see whether a row is decimal, binary, or a base unit.

FAQ

Frequently Asked Questions

What is the difference between MB and MiB?
MB is a decimal megabyte equal to 1,000,000 bytes. MiB is a binary mebibyte equal to 1,048,576 bytes. The names look similar, but the factors are different because decimal units use powers of 1000 and IEC binary units use powers of 1024.
How many bits are in a byte?
One byte is eight bits. File sizes are usually labeled in bytes or byte multiples, while network transfer rates often use bits or bit multiples. The converter includes both so users can see whether a value is being described as storage capacity or transfer quantity.
Why does disk capacity sometimes look smaller in an operating system?
Drive manufacturers often label capacity with decimal units such as GB or TB, while some operating systems report binary-style quantities. That difference can make a device appear smaller even before formatting overhead. Comparing GB with GiB makes the unit-system gap visible.
Which units should I use in documentation?
Use decimal labels such as MB and GB when the source or standard uses powers of 1000. Use binary labels such as MiB and GiB when the quantity is explicitly based on powers of 1024. Avoid using MB when the intended meaning is actually MiB.
Can this converter be used for transfer sizes?
Yes, if the value represents a quantity of data. For transfer rates such as megabits per second, convert the amount first and then divide by time, or use a dedicated bandwidth-rate converter when rate units are added.
About This Tool

About this data storage converter

Data storage conversion is easy to misunderstand because common labels are visually similar. A megabyte and a mebibyte are not the same quantity, and the difference grows as values move into gigabytes, terabytes, and petabytes. This converter keeps decimal and binary rows in one table so the distinction remains visible.

The tool normalizes every value into bits first. That makes bit-to-byte relationships explicit and helps when a file size, network transfer amount, disk label, or memory value moves between documentation systems.

The page is designed for practical technical work. A user can copy one selected result, but the surrounding table gives enough context to explain why another system may display a slightly different number.
