User’s Guide – 5
Dimension Keys
[Yds]
Yards — This is an entry and conver­sion key. The entry can be a whole number or a decimal number. Used with the [Conv] key converts any other dis­played dimensioned number to yards.
[Feet]
This is an entry and conversion key. The entry can be a whole number or decimal number. This key can also be used in conjunction with the [Inch] and [/] keys for entering values in Feet­Inch format. For example, 6 feet 9-1/2 inches is entered as follows:
6 [Feet] 9 [Inch] 1 [/] 2
Repeated presses of this key during conversions will toggle between Feet­Inch and Decimal Feet formats.
[Inch]
This is an entry and conversion key. The entry can be in whole or decimal numbers. This key can also be used in conjunction with the [/] key for enter­ing values in Fractional Inch format. Repeated presses of this key during conversions will toggle between Fractional Inch and Decimal Inch formats.
6 – ConcreteCalc™
[/]
Fraction Bar — This key is used to enter fractions. Fractions can be entered as proper (1 or less — 1/2, 1/8, 1/16) or improper (greater than 1 — 3/2, 65/64). For example, to enter 1/2, the key sequence would be: 1 [/] 2. If the denominator (the bottom number) is not entered, then the set fractional level (1/16, 1/2, etc.) is used. [Rcl] [/] displays the current fractional setting.
[Cu]
Cubic — This key is used with a dimen­sion key (feet, inches, yards, meters, etc.) to identify a value as being a vol­ume. Example: 5 [Cu] [Yds].
[Sq]
Square — This key is used with a dimension key (feet, inches, yards, meters, etc.) to identify a value as being an area. Example: 10 [Sq] [Feet].
[m]
Meters — This is an entry and conver­sion key used to enter decimal meters or to convert decimal meters from some other dimensional format (when used in conjunction with the [Conv] key).
User’s Guide – 7
[mm]
Millimeters — This is an entry and con­version key used to enter or to convert to decimal millimeters (when used in conjunction with the [Conv] key).
[Weight]
This key is used to convert a dimen­sioned cubic value or volume, to a weight value using the [Conv] key and the stored Weight per Volume (see below). For example, 5 [Cu] [Yds]
[Conv] [Weight] equals 7.5 tons, or 10 [Weight] (tons) [Conv] [Cu] [Yds] equals
6.666667 cubic yards. Repeated press­es of this key, after a cubic entry or conversion, will toggle between tons, pounds and kilograms.
[Conv] [%]
Weight per Volume — Used to set the Weight per Volume. Can be programmed as Tons per Cubic Yard, Pounds per Cubic Yard, or Kilograms per Cubic Meter. Default is 1.5 Tons/Cu. Yd. To set a dif­ferent weight per volume, for example, 2 Tons/Cu. Yd, press 2 [Conv] [%]. Value will be permanently stored. To recall stored value, press [Rcl] [%].
8 – ConcreteCalc™
Area/Volume Keys
[Length]
Enters the value for Length in dimen­sion problems (e.g., for calculating area or volume).
Note: This key is also used to
enter the length for “Square-ups” and the “Run” for stair problems.
[Width]
Enters the value for Width in dimension problems (e.g., calculating area or vol­ume).
Note: This key is also used to enter
the width for “Square-ups.”
[Height]
Enters the value for Height in dimen­sion problems (e.g., for calculating vol­ume).
Note: This key is also used to enter
the “Rise” for stair problems.
[Vol]
Volume — Computes the volume (Length x Width x Height) in Cubic Yards based on entered Length, Width and Height values. A second press will display the area (in square feet) based on entered Length and Width. Successive presses will toggle the display between the calculated area and volume.
[Conv] [Vol]
Area — Computes the area in Square Feet based on entered Length and Width.
User’s Guide – 9
Square-Up & Drop Keys
[Sq-Up]
Square-up — Enters or computes the “Square-Up” (or Diagonal) length based on entered Length and Width values.
[Drop]
Computes the total drop (or fall) over an entered Length, given an entered percentage drop or inch drop per foot value. Successive presses will act as a “constant add,” for displaying succes­sive drops.
Block/Footing Keys
[Block]
Number of Blocks — Computes the num­ber of blocks or bricks needed after enter­ing a wall area, or values entered in Length and Height.
[Conv] [Block]
Block Size — Used to permanently set the size of a single block or brick. The default size is 128 square inches for an 8” x 16” block. To recall the stored block area, press [Rcl] [Block].
[Ftg]
Footing — Used to compute concrete volume of footings, walls, curbs, etc.
10 – ConcreteCalc™
given an entered cross-sectional footing area (see [Conv] [Ftg]) and Length.
[Conv] [Ftg]
Cross-sectional Area — Used to perma­nently set the cross-sectional area for calculating footings. The default setting for the cross-sectional area is 1.8 square feet. To recall the stored cross-section­al area, press [Rcl] [Ftg].
Stair & Circle Keys
[Stair]
A multi-function key that displays the fol­lowing values when pressed repeatedly (using Length and Height values):
# Presses Information Displayed
1 Number of Risers 2 Riser Height 3 Riser Overage/Underage 4 Number of Treads 5 Actual Tread Width 6 Tread Overage/Underage 7 Stringer Length 8 Inclination Angle
When the [Stair] key is preceded by a linear or undimensioned entry, the value will be permanently stored as the
User’s Guide – 11
“Desired Riser Height”. Undimensioned values are assumed to be inches.
[Circ]
Circle — Based on an entered diameter, repeated presses display the following cir­cular values: 1) diameter, 2) area 3) cir­cumference.
[Conv] [Circ]
Arc Length — Used to find the arc length based on an entered diameter and angle. For example: 1 [Inch] [Circ] 180 [Conv]
[Circ] would display an Arc length of 1- 9/16 inches for an entered diameter of 1
inch and a 180° angle.

Positive/Negative Toggle — Toggles the sign of the displayed value between positive and negative.
[Conv] [ • ]
Per — Allows you to compute a total material cost given a unit dimension and an entered Per Unit Cost.
14 – ConcreteCalc™
Linear Dimensions
To enter dimensional values, enter the largest dimension first – feet before inch­es, inches before fractions. Enter fractions by entering the numerator (value above the line), pressing [/] and then the denominator (value below the line).
Note: If no denominator is entered, the default fraction setting is used. The exam­ples below show how to enter linear dimen­sions:
Dimension Keystrokes
5 ft 5 [Feet] 1/2 in 1 [ / ] 2 5 ft 1 in 5 [Feet] 1 [Inch]
5 ft 1-1/2 in 5 [Feet] 1 [Inch] 1 [ /] 2
10 yds 10 [Yds]
17.5 m 17.5 [m]
Note: Yards, meters and millimeters may only be entered as whole values (5 yards) or decimal values (5.5 meters), and not in combination with feet and inches or them­selves (5 meters, 8 millimeters). If a problem contains such a dimension, convert the yards (or meters) to “feet-inches” then add dimen­sions.
OPERATING BASICS
User’s Guide – 15
Square and Cubic Dimensions
Square and cubic dimensions are entered in the following order:
1) Numerical Value
2) Convention – Square or Cubic
3) Unit – Meters, Yards, Feet, Inches
Note: Feet–Inch format cannot be used to directly enter square or cubic values. By definition, this display format is a linear measurement. However, the area or volume can be found through simple multiplication.
The following examples show how to enter square and cubic dimensions:

Math Operations
Your calculator uses standard chaining logic. This means that you enter your first value, the operator (+, –, x, ÷), the second value, then the (=) sign.
3 [+] 2 [=] 5 3 [–] 2 [=] 1 3 [x] 2 [=] 6 3 [÷] 2 [=] 1.5
This feature also makes it easier to solve dimensional problems.
Adding Dimensions
Add 7 feet 3-1/2 inches to 11 feet 4 inches:
7 [Feet] 3 [Inch] 1[/] 2 [+] 11 [Feet] 4 [Inch] [=] 18 FT 7-1/2 IN
Add 11 inches to 2 feet 1 inch:
11 [Inch] [+] 2 [Feet] 1 [Inch] [=] 36 IN
Add 2 feet 1 inch to 11 inches:
2 [Feet] 1 [Inch] [+] 11 [Inch] [=] 3 FT 0 IN
Note: The format of the first value you enter determines the format of the answer. However, with the [Conv] key, you can change to any format you want, provided that you maintain convention.
