How to convert 1242 to hexadecimal

Step 1: Octal to decimal

Multiply each digit by 8 to the power of its position (0 on the right), then add:

Digit	Place value	Digit × place
`1`	8³ = 512	512
`2`	8² = 64	128
`4`	8¹ = 8	32
`2`	8⁰ = 1	2

512 + 128 + 32 + 2 = 674

Step 2: Decimal to hexadecimal

Divide by 16 repeatedly and keep the remainders. Reading the remainders from the last one to the first gives the hexadecimal digits:

Division	Quotient	Remainder (digit)
674 ÷ 16	42	`2`
