Math & Conversions

Data Storage Converter

Convert a data size between bits, bytes, KB, MB, GB, and TB using binary (1024-based) factors and 8 bits per byte.

What this calculator does

The Data Storage Converter estimates your result instantly from the values you enter, using standard math & conversions formulas. Convert a data size between bits, bytes, KB, MB, GB, and TB using binary (1024-based) factors and 8 bits per byte. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Data Storage Converter

This converter changes a data size from one unit to another across bits, bytes, KB, MB, GB, and TB. You enter a value, choose the unit you are converting from, and choose the unit you want the result in.

It treats one byte as 8 bits and steps between KB, MB, GB, and TB by factors of 1024 (binary), so the results match how storage capacities are commonly expressed in software.

Formula & Mathematical Calculation

Converted Value = f(Data Size, From, To)

Calculated according to standard math formulas implemented in the calculator core.

Calculation Example

Convert 1 GB to MB:

  • 1 GB = 1024 MB (each step up or down is a factor of 1024)

The calculator reports 1024 MB.

Key Benefits

  • Converts across six units from bits up to terabytes
  • Uses 1024-based steps between KB, MB, GB, and TB
  • Handles the 8-bits-per-byte relationship automatically

How to Use this Calculator

  1. Enter the data size
    Type the amount to convert into the 'Data Size' field.
  2. Choose the source unit
    Select the unit you are converting from in the 'From' dropdown (bit, byte, KB, MB, GB, or TB).
  3. Choose the target unit and calculate
    Select the unit you want in the 'To' dropdown, then press Calculate to see the converted value.

Assumptions & Limitations

What the calculation assumes

  • Every value you enter is treated as an exact, known amount.
  • Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
  • Results use standard published formulas and account only for the values entered above.
  • Rounding is applied for display; the underlying calculation uses your full precision.
  • Results are returned in the same units you enter, unless the tool states the output unit.

What it does not cover

  • Data Storage Converter produces a calculated result for reference and learning, not a certified or official measurement.
  • Real-world outcomes differ when tolerances, rounding rules or local standards apply.
  • Definitions and standards vary by region and change over time; verify the convention that applies to your case.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For work where the result carries real consequences, confirm it against an authoritative source.

Frequently Asked Questions

It uses 1024, so 1 KB equals 1024 bytes, 1 MB equals 1024 KB, and so on.

One byte equals 8 bits, so converting between bits and bytes uses that factor of 8.

Bit, byte, KB, MB, GB, and TB, in any from/to combination.
