Conversion Formula
The formula to convert a hexadecimal number to decimal is to multiply each digit by 16 raised to the power of its position index, starting at zero from the right. Then sum all those values.
Since hexadecimal uses 16 base, each place represents 16⁰, 16¹, 16², etc. For example, the hex number 7 has only one digit:
- 7 × 16⁰ = 7 × 1 = 7
Adding them gives 7, which is the decimal equivalent.
Conversion Example
- Hex: A
- A equals 10 in decimal.
- Calculation: 10 × 16⁰ = 10 × 1 = 10
- Result: 10 decimal.
- Hex: 1F
- Digit 1 is in the 16¹ place: 1 × 16 = 16
- Digit F equals 15 in decimal: 15 × 16⁰ = 15 × 1 = 15
- Sum: 16 + 15 = 31 decimal.
- Hex: 2B
- 2 × 16¹ = 2 × 16 = 32
- B equals 11 decimal: 11 × 16⁰ = 11 × 1 = 11
- Sum: 32 + 11 = 43 decimal.

Conversion Definitions
Hex: Hexadecimal is a base-16 numbering system uses sixteen symbols 0-9 and A-F, where letters represent values 10-15. It’s often used in computing to simplify binary data representation because each hex digit corresponds exactly four binary bits.
Decimal: Decimal is a base-10 numbering system uses digits 0 through 9. It is the standard system for denoting integer and non-integer numbers, the one most people use daily for counting and arithmetic, representing values by powers of ten.
Conversion FAQs
Why does hex 7 equal decimal 7?
Because hex digits 0-9 represent the same values as decimal digits 0-9, the hex digit 7 is identical to decimal 7. There’s no difference in this range, so no conversion alters its value.
Can hex values have negative numbers?
Hexadecimal numbers themselves are unsigned, but negative values can be represented using two’s complement notation when using fixed bit lengths. So negative hex numbers depend on the context of binary representation, not the numbering system itself.
How does the position of digits affect conversion?
Each digit’s position shows its power of sixteen. Digits left have increasing powers (16¹, 16², etc.), making their values higher. This positional value is multiplied by the digit to get its decimal contribution.
What if the hex input has letters like A or F?
Letters A through F correspond to decimal 10 to 15. When converting, these letters convert to numbers first before multiplying by the base power, then summed like digits.
Is it possible to convert decimal back to hex?
Yes, decimal numbers can be converted into hex by dividing the decimal number repeatedly by 16 and noting the remainders, which form the hex digits starting from the least significant digit.
