Base 13 to Base 21 Calculator

Welcome to our Base 13 to Base 21 Calculator, where you can calculate and convert the numeral system with a base 13 to the numeral system with a base 21.

Base 13 numbers are also known as Tridecimal numbers, and have thirteen different numbers and letters. The Base 13 numbers and letters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, and C.

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 13 is Tridecimal numbers, and Base 21 is Unvigesimal numbers, we can also call our Base 13 to Base 21 Calculator the Tridecimal to Unvigesimal Calculator.

Without further ado, please enter your Base 13 number below to have it converted to Base 21. (Remember, when entering your Base 13 number, you can only use the Base 13 numbers and letters outlined above.)

Convert  Base 13 to Base 21.
