Short cut way of Binary ↔Octal↔Hexadecimal

Binary ↔Octal↔Hexadecimal

Shortcut way of conversion the number system:

• Binary, Octal and Hexadecimal number systems are all powers of two (Which is the reason we use them) there is a relationship that we can exploit to make conversion easier.

                Ex: 1011010₂ = 132₈ = 5A₁₆

• To convert directly between binary and octal, group the binary bits into sets of 3 (because 2³ = 8) and use “0” left to the group if needed.

Ex:

• To convert directly between binary and hexadecimal number systems, group the binary bits into sets of 4 (because 2⁴ = 16) and use “0” in left if needed.
