DESCRIPTION
UnityCalc is a scientific calculator that includes both numbers and units in mathematical operations. This eliminates the need to convert to a consistent set of units when performing calculations. All of the unit conversions are handled automatically, even with mixed units. For example, 7 feet can be added to 2 meters directly, or 15 m/s can by multiplied by 1.5 hours. UnityCalc can also be used just as a unit converter or a standard scientific calculator.

FEATURES AND BENEFITS
* Faster calculations where mixed units are involved.
* Less error-prone calculations because unit conversion is handled automatically.
* Time saver for scientists, engineers, and students.
* Eliminates the need to lookup and convert units before performing calculations, just enter values in their native units.
* Easily enter units by typing their name or abbreviation like ft, kg, and Pa.
* Flexibility with unit names, for example hour, hours, hr, hrs are all acceptable.
* No long lists of units to select from.
* Unit expressions can be entered like kg*m/s^2 using familiar syntax.
* Units that result from calculations are reduced and simplified.
* Calculations are performed using the well-known method of Reverse Polish Notation (RPN). This is especially helpful when units are involved.
* RPN greatly simplifies complicated or long calculations.
* Hundreds of units are available.
* Many unit categories are available: length, time, mass, acceleration, force, volume, viscosity, power, area, amount, pressure, energy, frequency, rotation rate, speed, distance per volume, angles, temperature, prefixes, information, and electrical.
* Can be used without units for quick calculations.
* Can be used as a unit converter.
* Built-in Quick Start Guide with examples and list of all unit keywords.
