The Tradesman Calc 4400 is designed to be useful for both teaching technical trade math and for using on the job in a variety of settings requiring technical math; including Welding, Metal Fabrication, Engineering, Automotive Service Technology, Aviation and Drafting. It is ideal for people working in mathoriented trades and for students and instructors needing an easytouse handheld calculator with applied math functions.
With the Tradesman Calc you can work in and convert between all kinds of fractions – architectural (ruler) fractions (like 1/4 inch, 1/16 inch, etc.), proper fractions (2/3), mixed number fractions, (1 2/3) and improper fractions (5/3). You can also work in and convert between U.S. and metric dimensional math units – feetinchfractions, yards, decimal inches, meters, centimeters, millimeters, pounds, tons, grams, kilograms, metric tons, board feet, and dry ounces.
The calculator also has a wide range of powerful math functions, including the ability to enter math equations using order of operations. You can also work with exponents, square roots, reciprocals and more.
