You may want to practice getting a feel for your calculator keys
by reading through the key denitions and learning how to enter
basic feet-inch-fractions and metric, how to store values in
Memory, etc., before proceeding to the examples.
Order of Operations
Unlike other Calculated Industries calculators, which use the
Chaining Method of Operations, this calculator uses the Order
of Operation Method.
● Chaining Method (“as entered”): 10 + 4 x 5 = 70
● Order of Operations: 10 + 4 x 5 = 30
The Order of Operations method of computing is based on the
following order of precedence:
1) Expressions inside of parentheses
2) Single-variable functions that perform the calculation and
display the result immediately (trig functions, square,
square root, xy, percent, reciprocal, angle conversions)
3) Multiplication and division
4) Addition and subtraction
5) Equals (completes all operations)
If you need to calculate using the Chaining Method, you can
change this in your calculator Preference Settings.

Basic Function Keys
On/Clear Key – Turns on power. Pressing once
clears the last entry and the display. Pressing twice
clears all non-permanent values.
Off – Turns all power off. Clears all non-
permanent memory.
Arithmetic operation keys

– Keys used for entering
and numbers.
 Convert – Used with the dimensional keys to
convert between units or with other keys to access
special functions.
Store – Used for storing values.
Recall –Used with other keys to recall stored
values and settings.
 Memory Clear (M-R/C) – Clears Memory without
changing current display.
Accumulative Memory – Adds value to
Accumulative Memory.
 (M-) –Subtracts value from Accumulative Memory.
Dimensional Function Keys
Feet – Enters or converts to feet as whole or
decimal numbers. Also used with and keys
for entering feet-inch values (e.g., 
). Repeated presses during conversions toggle
between fractional feet-inch and decimal feet.

6 — Pl U m b i n G Ca l C ™ Pr o
Inch – Enters or converts to inches. Entry can be
whole or decimal numbers. Also used with for
entering fractional inch values (e.g., 
). Repeated presses during conversions toggle
between fractional and decimal inches.
Fraction Bar – Used to enter fractions. Fractions
can be entered as proper (1/2, 1/8, 1/16) or
improper (3/2, 9/8). If the denominator (bottom) is
not entered, the calculator’s fractional accuracy
setting is automatically used. Results are always
shown in typical building fractional format.

Defines the pipe material used for various pipe
sizes used in Pressure Loss calculations.
Defines the nominal Pipe Size being used.
 Denes the Pipe Type based on Pipe Material.
Enter or calculate volumetric Flow Rate through
a Pipe.
(Velocity) – Enter or calculate Velocity and convert
between feet per second, feet per minute and
meters per second.
Enter value for Force/Area calculations. Calculate
Pressure Loss. Convert between units of pressure.
Calculate Force and convert between lbf, newton.
Enter for Flow, Velocity, Pressure, Force
calculations. Calculate Area given values for Flow/
Velocity or Force/Area. If a Pipe Size has been
selected, Area will match Inside Dimension for pipe
of the current material and type.
Miscellaneous Functions
Displays value of π (3.141593).
(+/–) Toggle displayed value between minus and
plus value.
Clear All – Returns all stored values to the default
settings. (Does not affect Preference settings.)
