It excels in handling complex fractions, unit conversions between Imperial and Metric, and advanced trigonometric and geometric calculations. With dedicated keys for applied math problems and a safety-compliant battery design, it streamlines precision work in welding, metal fabrication, engineering, and drafting—saving time, reducing errors, and preventing material waste on every project. ## Description Product Description The Tradesman Calc 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 math-oriented trades and for students and instructors needing an easy-to-use handheld calculator with applied math functions. With the Tradesman Calc you can work in and convert between all kinds of tractions - 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 - feet-Inch-fractions, yards, decimal-Inch, meters, centimeters, millimeters, pounds, tons, grams, kilograms, metric tons, board feet, dry ounces. The calculator also has a wide range of powerful math functions, including the ability to enter math equations using order of operations. And you can work with exponents, square roots, reciprocals and more. The Tradesman Calc is a versatile and easy-to-use handheld calculator that will help you solve all kinds of math and geometry/trigonometry problems. Button-Cell Battery Safety Compliant Design -- This product uses a button-cell battery housed in a compartment secured with a tool-required fastener. The battery is not accessible during normal use without a tool, supporting alignment with applicable U.S. consumer product safety requirements for button-cell batteries. It includes a slide or Snap-On cover with attached Quick Reference Guide, an illustrated Pocket Reference Guide/User Guide stored in an onboard pocket (Spanish available as download), one long-life (CR2016) battery and a one-year limited .
