# Converting binary to hexadecimal

Posts: 3Member
I am not sure how to convert from the number to binary. I understand how to go from binary to hex once I have the binary number. I did the first one 100 and I got 00011001 can someone tell me if this is right and how to do the other two.

Binary--Hex
100
4340
2000

Like I said I think I have 100 right but can't figure out the other two.

Thanks so much,
Laura

The binary number 100 is 0x4 in hex. The 0x has no numerical meaning, it only designates it as hexadecimal.

To convert from binary to hex, just convert the binary number every 4 digits, starting from the least significant digit.

For example: 10000, rewrite as 00010000 and then split into fours 0001 0000. Then covert each grouping to hex: 0x10

1111001101011010 -> 1111 0011 0101 1010 -> 0xF35A

Hope that helps

its easy ex:

100/2=50 cary=0
50/2=25 cary=0
25/2=12 cary=1
12/2=6 cary=0
6/2=3 cary=0
3/2=1 cary=1
1/2=0 cary=1

now count bottom to top then = 1100100

do this way
