27 ÷ 16 = 1 remainder 11 (B)
1 ÷ 16 = 0 remainder 1
Now read the remainders from bottom to top:
438₁₀ = 1B6₁₆
Our Hex Converter performs this conversion automatically in a fraction of a second.
How to Convert Hexadecimal to Decimal
To convert hexadecimal into decimal, multiply each digit by its corresponding power of 16, then add the results.
Example: Convert 1A2 to Decimal
| Hex Digit | Power of 16 | Value |
|---|---|---|
| 1 | 16² | 256 |
| A (10) | 16¹ | 160 |
| 2 | 16⁰ | 2 |
256 + 160 + 2 = 418
Therefore:
1A2₁₆ = 418₁₀
