Conversion Formula

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

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

Step 1: Expand each digit of 132 (base 5) by position:

        1 × 5^2 = 25
        3 × 5^1 = 15
        2 × 5^0 =  2
        ────────────
        Sum = 42 (decimal)

Step 2: Divide 42 by 6 repeatedly (read remainders upward):

        42 ÷ 6 = 7  r 0
         7 ÷ 6 = 1  r 1
         1 ÷ 6 = 0  r 1
        Read remainders upward: 110

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

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.

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.
