Science Calculator  Free Version 3.4

This is a calculator that also acts as a science toolkit. The main calculator is a scientific calculator that is able to calculate molecular mass, and the system includes over 60 other calculators, converters and science tools. The system also contains numerous science data reference tables, flowcharts and a science glossary.

This is a freeware version of the full version of the DPLS Science Toolkit 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 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.

Data reference systems

• Number systems, counting of large numbers and significant figures.
• Sets symbols.
• Geometry symbols.
• Common graph equations.
• Atom structure.
• Resistor codes.
• Electron configuration values for all the elements.
• Metal reactivity.

Glossary system

A glossary system can be called that includes over 500 science terms, and over 150 math's and statistics terms.

The glossary system also contains the following: -

• Interactive tools to help remember terms commonly used in chemistry, physics, biology, maths and Earth science.
• A list of over 200 acronyms for computer and hardware.
• A list of over 1400 acronyms, abbreviations and symbols used in general communications.
• A list of over 1000 acronyms, abbreviations and symbols used in science.
• A list of over 500 fields of science and medicine.
