##### RJ Software’s FNA app is a multi-functional app for scientific calculation and unit conversion. The app is designed to implement four core operational modes. This includes statistics, base-n, trigonometry and unit conversion. Students in colleges and high schools, in particular, will find this utility software very useful in their mathematical and statistical calculations.

There are amazing ways and things you can do with FNA that you may not be aware of. Here are those you should find useful.

**Conversion Of Units**

This function is the major application almost everybody uses one time or another. With the unit conversion function, you can convert between Acceleration, Area, Angle, Energy, Density, Fuel Efficiency, Force, Energy, Length, Pressure, temperature and many other fundamental and derived units in physical sciences you can think of.

**Complex Calculations**

*Among the four major utilities of FNA software is Base-n.* This app can perform many difficult and complex mathematical problems such as operations involving gamma, factorial, permutations, combinations, logarithms, logic operations, trigonometric functions, among others.

**Enough Memory Capacity**

FNA app is built to give that privilege to save and recall between your sessions. It is designed with a 26 different memory register to save as much information as you may want to use later on in your calculation or data usage.

**Special Calculations**

You can find FNA app useful for special calculations. You can calculate heat index, get days between given dates and wind chills.

**Periodic Table **

Chemistry is an important aspect of physical sciences. **The FNA app now has a Periodic Table built in the app for reference purposes.** You can get very important data about a chemical element from this software. Basic data about an element such as atomic weight and other properties can be referenced from FNA software. Another notable feature is the metric prefix conversion that is designed in a drop-down style.

You can do a whole lot more with this app when you take time to apply every functions provided in the design. There are yet other alternatives you may want to consider on unit conversion and calculator apps.

**Alternatives**

**Qonverter**

**Qonverter is an utility software that gives you a 3-in-1 functionality.** It is a unit converter, a currency converter and also a calculator. It presents a clean interface with sidebars showing the various units such as acceleration, Density, force, Length, luminance, and the rest of others. It is available for free download for your Windows PC.

**ESBUnitConv**

**ESBUnitConv is a user-friendly app for conversion between unit measurements.** This includes units such as temperature, distance, area, pressure, velocity, radioactivity and Force.
