PDAcalc units is a conversion calculator that can quickly and easy translate different units of measure. It can translate days into seconds, Celsius into Fahrenheit, foreign currency into domestic currency, how many gallons a container of certain dimensions can hold, and much much more. When you first start PDAcalc units, a complete set of commonly used units is available for your calculations. Common base units include distance, mass, time, current, temperature, luminous intensity, substance and currency.

• Computing with units is simple
  Use '=>' to select which unit you want to convert to. For example if you would like to convert 4 miles into kilometers type: 4 mi => km and press EXE. To calculate how many gallons a container 1.2 yards wide, 2 feet deep and 11 inches high will hold type: 1.2yd*2ft*11in=>gal and press EXE. It is just that easy.
  Without the conversion symbol '=>' PDAcalc units will convert the result to the base unit. For example 110V * 16A will be converted to watts. And when you try to add incompatible units like feet to gallons, PDAcalc will let you know that the calculation is not valid.
  
  
• Helpful information
  You can easily add units that are not shown on the keyboard by selecting units from the help menu. After selecting a category a list of units will be shown. Those new units will then be shown in the appropriate category.
