## Overview

The Calculated Industries 4400 TradesmanCalc is a compact, professional-grade engineering calculator designed for tradespeople and technical students. 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 .

Review: Awesome calculator for the shop! - I've only scratched the surface of this one, but I already love it. Unlike many other Calculated Industries products, with many highly specialized functions, this is pretty much a standard scientific calculator that has the awesome ability to work directly in different units. It has trig, square, square root, etc. This is what I was looking for. You can work in US units, like: decimal yards, feet, inches feet+fractional inches fractional inches Also, others like pounds, kilograms, mm, m, etc. It has basic dimensional analysis. You don't just plug numbers in and hit a conversion key, it actually keeps track (to a point) of the units for you. For example, 25.4mm and 1 inch are basically the same thing. I can enter 25.4mm times 8 feet, and get a result in square feet - it's smart enough to know what you mean. It does not appear to let you mix units, like lb-ft, for example. It comes in a hard removable case, and has a well written instruction booklet that fits into a slot in the back.
Review: Great product - This product is very easy to use. It cones with a small user manual that fits in the back to help. Clearly marked buttons make it easy to use

## Features

- SOLVE ALL FRACTIONS EASILY in multiple formats so you can calculate actual measurements with plan requirements and determine the new work piece size; work in standard fractions or figure out proper fractions, or determine mixed number and improper fractions; depending on your work requirement you can convert between decimal and fraction display results
- GET ANSWERS TO APPLIED MATH problems and convert between Imperial and metric units to make calculations straightforward; perform critical unit conversions when you have a plan marked in Imperial measurements and your work material is in metric; you can enter math equations using order of operations to get the right answer no matter the project
- TRIG FUNCTIONS GET STRAIGHT TO THE ANSWER for angle and side problems; use dedicated keys to enter and solve circle, arc, radius hexagonal and polygonal dimensions; you just need to know your project’s measurements, the calculator handles the relationship between particular quantities and units. It also solves proportions and ratios.
- HELPS YOU PREVENT COSTLY MATERIAL WASTE with built-in solutions for welding, metal fabrication, engineering, drafting and more; you can also determine lengths, weights, angles and board feet totals for your material order requirements; the calculator minimizes the math, helping you get the answer you need for your work without fighting through equations
- INVALUABLE' TOOL PAYS FOR ITSELF DAILY by reducing headaches, saving time and preventing expensive material errors on all your projects, from the office to the shop floor or in the field. Comes with a protective slide cover, quick reference and pocket reference guide (stores in calculator), one long-life battery and full one-year limited
- REESE’S LAW COMPLIANT BATTERY DESIGN – Button-cell battery compartment is secured with a tool-required fastener to help prevent unintended access and align with current U.S. federal safety requirements (16 CFR Part 1263). Battery compartment remains secured during normal use, transport, and handling.
