Dimension Keys
[Yds]
Yards — This is an entry and conversion key (when used with [Conv]).
The entry can be a whole number or a
decimal number.
[Feet]
This is an entry and conversion key
(when used with [Conv]). The entry
can be in whole or decimal numbers.
This key can also be used in conjunction with the [Inch] and [/] keys for
entering values in Feet-Inch 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 Feet-Inch 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
with the [/] key for entering values in
Fractional Inch format. For example,
enter 9-1/2 inches as: 9 [Inch] 1 [/] 2.
Repeated presses of [Inch] during conversions, toggles between Fractional
Inch and Decimal Inch formats.

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.
[Rcl] [x]

dimension key (feet, inches, yards,
meters, or millimeters) to identify an
area value. Example: 10 [Sq] [Feet].
User’s Guide – 7
[m]
Meters — This is an entry and conversion key used to enter decimal meters
or, when used with [Conv], to convert
to decimal meters from some other
dimensional format.
[mm]
Millimeters — This is an entry and
conversion key used to enter decimal

[Conv] [Weight] equals 7.5 tons, or 10
[ We i g h t ] (tons) [Conv] [Cu] [Yds]
equals 6.666667 cubic yards. Repeated
presses of this key, after a cubic entry
or conversion, toggles among tons,
pounds and kilograms.
[Conv] [%]
Weight per Volume — Used to set the
Weight per Volume. Can be pro grammed as Tons per Cubic Yard,
Pounds per Cubic Yard, or Kilograms
per Cubic Meter. Default is 1.5 Tons
per Cubic Yard. To set a different
weight per volume, for example, 2

[%]. Value will be permanently stored.
To recall stored value, press [Rcl] [%].
Area/Volume & Angle Keys
[Length]
Enters the value for length in dimension problems (e.g., for calculating
area or volume).
[Conv] [Length]
Square-up — Computes the diagonal,
or “square-up,” based on entere d
length and width.
[Width]
Enters the value for width in dimension problems (e.g., for calculating
area or volume). Also computes width
from entered values of depth and percent grade or slope.
[Conv] [Width]
Percent Grade — Used to enter and
display percent grade. Also computes
percent grade using entered values for
width and depth, or slope.

volume). Also computes depth from
entered values of width and percent
grade or slope.
User’s Guide – 9
[Conv] [Depth]
Slope — Used to enter slope as a ratio
of run per unit rise (e.g., 4:1), or in
decimal degrees (e.g., 10°). Also computes slope using entered value for
width and depth, or percent grade.
Note: Only works with width. Does not
operate in conjunction with length.
[Vol]
Volume — Computes the volume (in
cubic yards) based on entered length,
width and depth 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.
Excavation/Volume Keys
[Cut/Fill]

USING THE HEAVYCALC
Linear Dimensions
To enter dimensional values, enter the
l a rgest 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 exam ples below show how to enter linear
dimensions:
Dimension Keystrokes
5 Feet 5 [Feet]
1/2 Inch 1 [ / ] 2
5 Feet 1 Inch 5 [Feet] 1 [Inch]
5 Feet 1-1/2 Inch 5 [Feet] 1 [Inch] 1 [ /] 2
10 Yards 10 [Yds]
17.5 Meters 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 them selves (5 meters, 8 millimeters). If a p ro b lem contains such a dimension, convert the
y a rds (or meters) to “feet-inches” then add
d i m e n s i o n s .
14 – HeavyCalc™
Square and Cubic Dimensions
S q u a re 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 vol ume can be found through simple multipli cation.
The following examples show how to
enter square and cubic dimensions:
