Base 8 to Base 21 Calculator




Welcome to our Base 8 to Base 21 Calculator, where you can calculate and convert the numeral system with a base 8 to the numeral system with a base 21.

Base 8 numbers are also known as Octal numbers, and have eight different numbers. The Base 8 numbers are 0, 1, 2, 3, 4, 5, 6, and 7.

Base G 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.

Since Base 8 is Octal numbers, and Base 21 is Unvigesimal numbers, we can also call our Base 8 to Base 21 Calculator the Octal to Unvigesimal Calculator.

Without further ado, please enter your Base 8 number below to have it converted to Base 21. (Remember, when entering your Base 8 number, you can only use the Base 8 numbers outlined above.)

Convert  Base 8 to Base 21.
