Frequently Asked Questions

Hexadecimal to decimal conversion is the process of converting a base-16 number to a base-10 number. Each hex digit is multiplied by 16 raised to the power of its position, and the results are summed.
Multiply each hex digit by 16 raised to its positional power (starting from 0 on the right). For example, hex 1A = (1 × 16¹) + (10 × 16⁰) = 16 + 10 = 26 in decimal.
Hex FF equals decimal 255. F = 15, so FF = (15 × 16) + 15 = 240 + 15 = 255.
Hexadecimal uses 16 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. The letters A–F represent decimal values 10–15 respectively.
A hex color code like #FF5733 is split into three pairs: FF (red), 57 (green), 33 (blue). Each pair is converted from hex to decimal: FF=255, 57=87, 33=51, giving RGB(255, 87, 51).
Hexadecimal is used in programming because it concisely represents binary data — each hex digit maps to 4 bits. It is widely used for memory addresses, color codes, bitmasks, error codes, and data encoding.
