How do you convert decimal 6640625 to its hexadecimal?

Answer 1

The way I convert between decimal and hexadecimal is to first convert the decimal number to binary:

664062510 = 110010101010011111100012

Then split the binary number into 16-bit (4 digit) chunks:

0110 0101 0101 0011 1111 00012

Next, convert each chunk into a hexadecimal digit:

0110 0101 0101 0011 1111 00012

6 5 5 3 F 1

Finally, put all the digits together:

664062510 = 6553F116
