CalcPad was designed to take full advantage of the computer screen, keyboard, and mouse. In the past many people tried to simulate calculators as closely as possible. They would even purposely add limitations to make it behave more like a regular calculator. CalcPad stores the value of previous lines in different ways. Keep in mind that any line that uses 'total' or 'sum' is defined as a 'total line' or 'sum line'. So a line that just says 'total' or a line that says 'total + 500' are both considered to be a 'total line'.
Calcpad version 3.0 already supports some non-metric units, that are commonly used in science, technology and engineering. A list of currently supported units is available in Units section of the User manual. More units can be easily appended in the next version. We will appreciate your suggestions very much.
You can download the latest version from the following link:
Calcpad supports both Imperal and USCS system. Some of the units have slightly different values although their names are the same. You can select which system to use by switching the respective option in the program window (●Imperial/○US).

You can convert between metric and non-metric units. That is possible because both systems exist simultaneously inside the Calcpad core engine. You can also mix them in one and the same expression. Open Calcpad on your desktop or go to the online calculator and try the following examples:
2ft + 3in|cm
Calcpad 200
kg/lb
You will get the following answer in the output window:
2ft + 3in = 68.58cm
kg/lb = 2.204623

Converting temperatures is a little bit more tricky because the origins of the different temperature scales are not the same. For example: 0°C = 32°F. Because of that, it makes a difference whether you convert between absolute values or temperature differences. In the next post, we will discuss more about this and how this problem is solved in Calcpad.
