How to Calculate Hexadecimal?

Hexadecimal (base-16) is a number system that uses 16 symbols: 0-9 and A-F. It's commonly used in computer programming and digital systems. Each position represents a power of 16.

Converting Hexadecimal to Decimal:

• Write down the hexadecimal number
• Multiply each digit by 16 raised to the power of its position (from right to left, starting at 0)
• Add all the results together

0xFF = 15×16¹ + 15×16⁰ = 240 + 15 = 255

Converting Decimal to Hexadecimal:

• Divide the decimal number by 16
• Write down the remainder (convert 10-15 to A-F)
• Continue dividing the quotient by 16 until it becomes 0

255 ÷ 16 = 15 remainder 15 → F

15 ÷ 16 = 0 remainder 15 → F

Result: 0xFF
