How this calculator works

Converted value = input × source unit factor ÷ destination unit factor.

Before you use the result

  • KB/MB/GB are decimal; KiB/MiB/GiB are binary.

What is Data Storage Converter?

Data Storage Converter helps you convert data sizes with an explicit decimal or binary unit choice.

The main result is converted value, with a breakdown of conversion factor. The formula, example and assumptions below explain how to interpret it.

How to use Data Storage Converter

Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.

  1. Gather value, from unit and to unit. Use values from the same situation or reporting period.
  2. Replace the example value with your own value, then complete the other fields. Check the displayed units and each selected option.
  3. Select Calculate and read converted value with its result breakdown. Change one input and calculate again to compare a second scenario. Reset restores the original example.
  • Enter value, at least 0. Decimals are accepted.
  • Choose from unit from bytes, bits, KB, MB, GB, TB, KiB, MiB and GiB.
  • Choose to unit from bytes, bits, KB, MB, GB, TB, KiB, MiB and GiB.

Data Storage Converter: a worked example

With the inputs below, the result is 8 bits (converted value). Follow the example, then replace these illustrative values with your own.

Understanding the Data Storage result

Read converted value alongside conversion factor. These describe different parts of the same calculation.

Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.

  • Example Conversion factor: 8

Data Storage Converter: assumptions and common mistakes

A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.

  • KB/MB/GB are decimal; KiB/MiB/GiB are binary.
  • Select the correct unit system. US and imperial gallons differ, local land units vary, and exchange rates need a dated source.

Data Storage Converter FAQs

What does Data Storage Converter calculate?

Data Storage Converter helps you convert data sizes with an explicit decimal or binary unit choice. Its main output is converted value in bits.

What inputs do I need for Data Storage Converter?

You need value, from unit and to unit. Use the field labels and units to match your figures to the formula.

Which formula does Data Storage Converter use?

Converted value = input × source unit factor ÷ destination unit factor.

What is a worked example for Data Storage Converter?

Example inputs: Value: 1; From unit: bytes; To unit: bits. The result is 8 bits (converted value).

How should I enter value?

Enter value, at least 0. Decimals are accepted.

How do I choose from unit?

Choose from unit from bytes, bits, KB, MB, GB, TB, KiB, MiB and GiB. The example uses bytes; replace it if your circumstances differ.

How should I read converted value?

Read converted value alongside conversion factor. These describe different parts of the same calculation.

Why might my Data Storage Converter result differ from my records?

KB/MB/GB are decimal; KiB/MiB/GiB are binary. Differences in entered values, units or rounding can also change the comparison.

Can I compare two scenarios in Data Storage Converter?

Yes. Note your first converted value, change value or another input, and select Calculate again. Editing a field clears the old result so it is not mistaken for a new calculation.

Is Data Storage Converter free, and where are my inputs calculated?

This calculator is free to use without signing in. Its formula runs in your browser; calculator inputs are not sent to a calculation API. The inputs reset to the example values when you reset the form or start a fresh page.
