Base 21 to Base 18 Calculator




Welcome to our Base 21 to Base 18 Calculator, where you can calculate and convert the numeral system with a base 21 to the numeral system with a base 18.

Base 21 numbers are also known as Unvigesimal numbers, and have twenty-one different numbers and letters. The Base 21 numbers and letters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, I, J, and K.

Base G numbers are also known as Octodecimal numbers, and have eighteen different numbers and letters. The Base 18 numbers and letters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, and H.

Since Base 21 is Unvigesimal numbers, and Base 18 is Octodecimal numbers, we can also call our Base 21 to Base 18 Calculator the Unvigesimal to Octodecimal Calculator.

Without further ado, please enter your Base 21 number below to have it converted to Base 18. (Remember, when entering your Base 21 number, you can only use the Base 21 numbers and letters outlined above.)

Convert  Base 21 to Base 18.
