Frequently asked questions
How do I convert a binary number to decimal?⌄
Simply type your binary number (e.g. 1010) in the "Binary" field. The corresponding decimal value (10) appears immediately in the "Decimal" field.
What are valid characters for hexadecimal?⌄
Hexadecimal accepts digits 0–9 and letters A–F (or a–f). The tool automatically converts to uppercase. Example: FF = 255 in decimal.
What is nibble spacing in binary?⌄
Nibble spacing splits the binary representation into groups of 4 bits (e.g. 1111 0000 instead of 11110000). This is a common convention in electronics and low-level programming to improve readability.
Is there a size limit for numbers?⌄
The tool uses JavaScript's parseInt(), limiting it to integers up to 2^53 - 1 (Number.MAX_SAFE_INTEGER). For very large numbers, a dedicated Big Integer tool would be required.
