Base 18 to Base 9 Calculator

Welcome to our Base 18 to Base 9 Calculator, where you can calculate and convert the numeral system with a base 18 to the numeral system with a base 9.

Base 18 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.

Base G numbers are also known as Nonary numbers, and have nine different numbers. The Base 9 numbers are 0, 1, 2, 3, 4, 5, 6, 7, and 8.

Since Base 18 is Octodecimal numbers, and Base 9 is Nonary numbers, we can also call our Base 18 to Base 9 Calculator the Octodecimal to Nonary Calculator.

Without further ado, please enter your Base 18 number below to have it converted to Base 9. (Remember, when entering your Base 18 number, you can only use the Base 18 numbers and letters outlined above.)
