Conversion Formula

Step-by-step example using the value 42 (decimal):

Convert Base 6 (base 6) → Base 5 (base 5)

Step 1: Expand each digit of 110 (base 6) by position:

        1 × 6^2 = 36
        1 × 6^1 =  6
        0 × 6^0 =  0
        ────────────
        Sum = 42 (decimal)

Step 2: Divide 42 by 5 repeatedly (read remainders upward):

        42 ÷ 5 = 8  r 2
         8 ÷ 5 = 1  r 3
         1 ÷ 5 = 0  r 1
        Read remainders upward: 132

────────────────────────────
Result:  110 (base 6) = 132 (base 5)

About Base 6

Senary (base 6) uses digits 0-5. Each position is a power of 6: 6⁰=1, 6¹=6, 6²=36. Six is divisible by 1, 2, 3, and 6, making fractions clean: 1/2 = 0.3, 1/3 = 0.2 (both terminating). Native to the Ndom language of Papua New Guinea. Standard dice produce one uniform senary digit per roll. Donald Knuth noted senary's compact multiplication table. Conversion: decimal 42 = 1×36+1×6+0 = 110₆.

About Base 5

Quinary (base 5) uses digits 0-4. Each position is a power of 5: 5⁰=1, 5¹=5, 5²=25. One of the most historically widespread alternative bases, reflecting one-hand finger counting - Proto-Indo-European *penkwe = 'five/fist'. Tally marks group strokes in fives. Babylonian sexagesimal (base 60) used a 5×12 sub-structure. Fibonacci numbers mod 5 have Pisano period 20. Conversion: decimal 42 = 1×25+3×5+2 = 132₅.
