Features

The calculator is highly useful for both students and science professionals.

The calculator will operate on a desktop, laptop or notebook with Internet Explorer installed.

No connection to the Internet is necessary.

The file to be downloaded is approximately 8 MB in size.

The system is specifically designed for ease of use.

A help system is available to explain calculator functions and operation.

The main calculator has over 20 functions and includes the ability to store and recall up to 10 values.

All calculations performed by the calculator are recorded in a note pad area for cutting and pasting elsewhere.

The calculator can determine the molecular weight of a compound by typing its formula.
