One hexadecimal digit corresponds exactly to four binary digits. To convert from hexadecimal to binary: Simply replace each hexadecimal digit with four binary digits.

This can also be used in reverse.
Example:
Convert the binary number 1010 0011 1111₂ to hexadecimal.
1010 0011 1111₂ = 10₁₀ 3₁₀ 15₁₀ = A3F₁₆ in hexadecimal.
