About Sexagesimal (Base-60)
The sexagesimal system uses 60 as its base. It was developed by the ancient Sumerians and passed down to the Babylonians. Its legacy persists today in how we measure time (hours, minutes, seconds) and angles (degrees, minutes, seconds).
This tool uses a modern comma-separated format, where 1, 6, 40 represents 1×60² + 6×60¹ + 40×60⁰.

Positional Notation
Sexagesimal is a positional numeral system with a base of 60. Each position represents a power of 60, increasing from right to left.
For a number represented as a, b, c:
The total value is calculated as:
(a × 60²) + (b × 60¹) + (c × 60⁰)
(a × 3600) + (b × 60) + (c × 1)
Example: For the sexagesimal number 2, 25, 4
(2 × 3600) + (25 × 60) + (4 × 1)
7200 + 1500 + 4 = 8704 (in decimal)
