Calculate from binary to decimal

1. Every number in a binary code stands for a whole decimal number
2. The numbers are (from right to left) 1, 2, 4, 8, 16, 32… and so on (always multiplied with 2)
3. Now take all the decimal numbers where there is a “1” in the binary code
4. Add up all of them and you get your decimal number

A binary number is expressed in the base-2 numeral system. This means it only consists of zeros and ones. Binary numbers are mostly used in digital electronics.

Calculate from decimal to binary

1. Divide your decimal number by 2
2. If there is a “.5” at the end, take it away and write “rest 1”
3. Now do the same thing with the result from step 2
4. Keep doing all the steps above until you get 0
5. All the “0” and “1” you got (from end to beginning) is now your binary number
