Welcome to our Base 21 to Base 4 Calculator, where you can calculate and convert the numeral system with a base 21 to the numeral system with a base 4.
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 Quaternary numbers, and have four different numbers. The Base 4 numbers are 0, 1, 2, and 3.
Since Base 21 is Unvigesimal numbers, and Base 4 is Quaternary numbers, we can also call our Base 21 to Base 4 Calculator the Unvigesimal to Quaternary Calculator.
Without further ado, please enter your Base 21 number below to have it converted to Base 4. (Remember, when entering your Base 21 number, you can only use the Base 21 numbers and letters outlined above.)
Below is a list of the first one hundred Base 21 numbers that we have converted to Base 4 for you, so you can see the pattern.
