Almost always people use numbers with a base of 10. But should you be working base 2 (Binary numbers), base 8 (Octal), or base 16 (Hexadecimal), CalGraph will convert from one system to another.

Click Utilities and then Conversions.

Holding the Control key and typing q has the same result.

In the Conversions window select Number Systems.

Click the kind of number you have in the Units From: box, and the kind of number you want in the

Units To: box.

Enter the number in the lower left box and click Convert.

This window shows that the Binary number 1000 is written 8 in base 10.
