number or a decimal num-
ber. Used with the Çkey
converts any other dis-
played dimensioned num-
ber to Yards.

f Feet Key — Enters or con-
verts to Feet as whole or
Decimal numbers. Also
used with the iand /
keys for entering Feet-Inch
values (e.g., 6 f 9 i
1 / 2). Repeated press-
es during conversions tog-
gle between Decimal Feet
and Feet-Inch-Fractions.
i Inch Key — Enters or con-
verts to Inches . Entry can
be whole or Decimal num-
bers. Also used with the /
key for entering Fractional
Inch values (e.g., 9 i 1
/ 2). Repeated presses
during conversions toggle
between Fractional and
Decimal Inches.
/ Fraction Bar Key — Used
to enter Fractions . Fractions
can be entered as proper
(1/2, 1/8, 1/16) or improper
(3/2, 9/8). If the denomina-
tor (bottom) is not entered,
the calculator's fractional
accuracy setting is automat-
ically used.

C Cubic Key — This key is
used with a dimension key
(Feet, Inches, Yards,
Meters, etc.) to identify a
value as being a volume.
Example: 5 C y
S Square Key — This key is
used with a dimension key
(Feet, Inches, Yards,
Meters, etc.) to identify a
value as being an area.
Example: 1 0 S f
m Meter Key — Enters or
converts to Meters.
M Millimeter Key — Enters or
converts to Millimeters.
w Weight Key — Enters or
converts (a volume value) to
Tons, Pounds or Kilograms .
Repeated presses will cycle
through these units.
Ç % Weight/Volume — Enters
or converts the Weight
per Volume setting as
Tons/Yard3, Lbs/Yd3 or
kg/m3 . Repeated presses
will cycle through these
settings.

Area/Volume Keys
l
Length Key — Enters the
value for Length in dimen-
sion problems (e.g., for cal-
culating Area or Volume).
Note: this key is also used to
enter the length for “Square-
Ups.”
Ç l Square-Up — Calculates
the Diagonal, or “Square-
Up,” based on entered
Length and Width.
W
Width Key — Enters the
value for Width in dimension
problems (e.g., calculating
Area or Volume).

POCKET REFERENCE GUIDE — 8
Ç d 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 calculates Slope
using entered value for
Width and Depth or Percent
Grade.
v Volume Key — Computes
the Volume (Length x Width
x Depth) 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 dis-
play between the calculated
Area and Volume.
Ç v

in Square Feet based on
entered Length and Width.
Excavation/Volume Keys
FUsed to enter or calculate
the cut or fill amount. Based
on entries of proposed and
existing benchmarks. A fill
is displayed as a positive
value; a cut as a negative
value.

e Existing Key — Used to
enter or calculate an exist-
ing benchmark, Grade or
value.
p
Proposed Key — Used to
enter or calculate a pro-
posed benchmark, Grade
or value.
b
Bank Volume Key —
Enters or calculates the vol-
ume for bank fill material.
Bank fill is material in an
untouched, pristine state.
ç
Compacted Volume Key
— Enters or calculates the
volume for compacted fill
material. Compacted fill is
material that has been
compacted.
Ç ç
% Shrink — Enters or
recalls percent shrink factor
for converting between bank
and compacted fill volumes.

ume for loose fill material.
Loose fill is material that
has been disturbed or
excavated.
Ç L
% Swell — Enters or recalls
the percent swell factor used
for converting between
