TechSheet is a technical spreadsheet intended for use by scientists, engineers and technicians. This spreadsheet allows for calculations that incorporate units of measure with its associated value within each individual cell. Numerical manipulations are accomplished in a fashion that ensures consistent units of measure and automated unit conversions. The full set contains over 500 different types of units including simple ones like length and time, and complex units like power and magnetic flux. Like any good scientist, TechSheet is aware of the rules for calculating with units; so for instance if a "length" is multiplied by a "length", TechSheet will show an "area" result (meters * meters results in square meters). The software includes graphic capabilities that are also aware of the measurement units. The demo software has some limitations but is still quite handy for a considerable range of technical problems. Techsheets spreadsheet format makes it easy to learn and its use of measurement units make it a powerful technical tool.
