Tradesman CalC™
The Tradesman Calc™ Trades Math
and Conversion calculator 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. 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 Architectural (ruler) fractions
(1/4 inch, 1/16 inch, etc.), proper
fractions (2/3), mixed number
fractions (1-2/3) and improper
fractions (5/3)
•
Solve dimensional math problems,
and convert between U.S. and
metric dimensional math units
• Solve angle and side problems with
trigonometry
• Enter and solve circle, arc, radius,
hexagonal and polygonal dimensions
• Convert between decimal and
fraction
• Enter and solve ratios and
proportions

• Enter math equations using
parentheses
• Work with exponents
Use it in the classroom or on the job for
solving math and design problems in –

SETTING fRACTIoNAL
RESoLUTIoNS
The Tradesman Calc is set to display
fractional Inch answers in 64ths of
an Inch. All examples in this User’s
Guide are based on 1/64". However,
you may select Fractional Resolution
to be displayed in other formats (e.g.,
1/16", 1/32", etc.). The methods for
permanently and temporarily changing
Fractional Resolution are shown in the
following sections.

Permanently Set Fractional

To permanently set the Fractional
Resolution, you must be in

You can also convert a fractional value
to a different resolution temporarily
while solving a problem. In the example
below, add 1/64th to 44/64th of an Inch
and then convert the answer to other
