number bases
A useful tool for number base conversion
What is the Base Conversion Utility?
The Base Conversion Utility is a self-contained, embeddable web component that allows users to convert numbers between different numerical bases, from unary (base 1) to hexadecimal (base 16).
How to Use
Select Bases: Use the dropdown menus to select the 'from' and 'to' bases. (If enabled).
Enter Value: Type or paste a number in the 'From' box. Valid characters for the base will appear green, invalid ones red.
View Output: The 'To' box will update automatically with the converted value. It will show an error if the input is invalid.
Copy Result: Click the "Copy" icon (next to the "To" field) to copy the converted value to your clipboard.
Group Binary: If the 'To' field is Base 2 (Binary), a "Group" checkbox will appear. Toggling this will group the binary number into 4-bit nibbles for readability.
Show Steps: Check the "Show Steps" box to see a detailed breakdown of the conversion calculation.
Change Method: If converting between power-of-2 bases (2, 4, 8, 16), a "Method" dropdown will appear, letting you switch between the clear "Educational" (Base 10 pivot) method and the "Direct (Shortcut)" grouping method.
Scroll Long Numbers: If a number is too long to fit, click the left/right arrows inside the field to scroll.
Swap: Click the swap icon (two arrows) to swap the 'from' and 'to' bases and values. (This button is disabled if the input is invalid).
Shortcuts: Click the shortcut buttons (e.g., "Dec ➔ Hex") to quickly set the bases for common conversions.
