HOW TO CONVERT

1
Hexadecimal (base 16) uses digits 0-9 and letters A-F, where A=10, B=11, C=12, D=13, E=14, F=15.
2
27 / 16 = 1 remainder 11 (B) 1 / 16 = 0 remainder 1 (1) Read hex digits bottom to top: 1B
3
The result is 1B, written as 0x1B in programming notation or 1B₁₆ in mathematical notation.
4
Verify: 1 x 16^1 + 11 x 16^0 = 27. ✓
