DPLS Science Calculator Free version information

This program acts as a science toolkit, and contains a scientific calculator that is able to calculate molecular mass, and over 60 other calculators, converters and science tools.

The calculator also contains numerous science data reference systems and a science glossary system.

The program is a freeware version of the DPLS Science Toolkit that is available from the purchasing page.

Requirements to use

The program requires a PC with Internet Explorer installed. The program does not require any other software, and does not require connection to the Internet. The program will readily run from a USB.

The file to be downloaded is approximately 6.1 MB in size.

Functions of the calculator

The main scientific calculator performs the normal functions of a scientific calculator, and is also able to calculate atomic mass and molecular mass. This enables the molecular formula of a molecule to be incorporated into an equation for calculation.

For example: - Entering 4 * H2O gives the molecular mass of 4 mol of water molecules.

All calculations performed by the calculator are recorded in a note pad area for cutting and pasting elsewhere. The calculator also has a text pad area where a longer calculation can be prepared before cutting and pasting into the calculator. Drop down lists can be used to write information into the text pad area.

These drop down lists include: -

A list of over 300 common compounds with their chemical name, CAS number, molecular formula and molecular mass.
A list of elements with their atomic numbers, element name and symbol.
A list of over 50 constants.
A list of SI prefixes.

Other calculators, converters and science tools can be called including the following: -

A triangle calculator that calculates length of sides, angles and area of a right triangle and an oblique triangle.
A set of vector addition calculators.
An extensive measurement converter with over 50 categories.
An area and volume calculator for common two dimensional and three dimensional objects.
A percentage and fraction calculator.
A comprehensive angle converter and hyperbolic converter.
A gas laws calculator.
A molar mass and molarity calculator for common acids, base and compounds.
An event timer that displays a report.
An interactive database of over 20 properties for each element in the periodic table.
A half-life calculator.
Interactive flowcharts of electrical and mechanical derived quantities, with a popup calculator and a description of each derived quantity.
Over 60 equation calculators that will solve for any variable in the equation.

These calculators are grouped under motion, force, energy, gases, area and volume, electricity, waves, light and chemistry.
