Dimensional Unit Keys

y - Yards KeyEnters or converts to Yards.

f - Feet KeyEnters or converts to Feet as wholeor decimal numbers. Also used withthe i and / keys for enteringFeet-Inch-Fraction values (e.g., 6f 9 i 1 / 2 ). Repeatedpresses during conversions togglebetween Feet-Inch-Fractions andDecimal Feet.

KEY DEFINITIONS


i - Inch KeyEnters or converts to Inches. Entrycan be whole or decimal number.Also used with the / key for enteringFractional Inch values (e.g., 9 i1 / 2 ). Repeated presses duringconversions toggle betweenFractional and Decimal Inches.

/ - Fraction Bar KeyUsed to enter fractions. Fractionscan be entered as proper (1/2, 1/8,1/16) or improper (3/2, 9/8).

m - Meter KeyEnters or converts to Meters.

Convert Key Functions

Ç - Convert KeyUsed with the dimensional unit keysto convert between dimensions, theProject Keys to calculate materialquantities, or with other keys toaccess special functions.

Ç x - Clear AllClears all stored values and sets cal-culator back to defaults.

Ç / - Percent (%)Four-function (+, -, x, ÷) percent.


Ç – - Change Sign (+ / -)Toggles displayed value to positive ornegative. (Repetitive presses of Ç– will change sign from positive ornegative.)

Ç ÷ - Square RootFinds Square Root of value in display.

Ç + - x2

Finds Square of value in display.

Ç s - Pi (π)Constant 3.141593.

Memory

s m (M+) - Adds or stores a valuein the semi-permanent memory (e.g.,1 5 0 s m). Semi-permanentmeans the value is cleared when thecalculator is turned off.

Ç – s m (M-) - Subtracts avalue from the semi-permanentMemory (e.g., 1 5 0 Ç – sm subtracts 150 from the memory).

r m (M-R/C) - Recalls Memory value(e.g., if 150 has been stored in Memory,pressing r m will display 150).

r r - Displays and clears Memoryvalue.


Entering Square or Cubic

To label a dimension as “Square” or“Cubic,” enter the value, then press thedesired dimension key twice forSquare and three times for Cubic. Forexample, to enter 25 Cubic Yards,press 2 5 y y y.

Fraction Resolution

Your calculator is set to display Fractionalvalues to the nearest 16th of an Inch(default setting). Press r / to accessthe fraction resolution setting. Repeatedpresses of / will then revolve throughthe available settings: 1/16, 1/32, 1/64,1/2, 1/4 and 1/8. Press o to exit.

Project Keys

p - PaintCalculates volume of paint, based onan entered area and a stored PaintCoverage per Gallon (see below).Finds quantity in Gallons, Quarts orPints upon repeated presses.

s p - Stores Paint CoverageStores Paint Coverage per Gallon. Torecall this setting, press r p.Default is 350 sq.ft. per gallon.

t - TileFinds the number of tiles, based onan entered area and a user-storedGrout Width (see below). Repeatedpresses will scroll between numbersof tiles for various “standard” tilesizes (18”, 16”, 13”, 12”, 10”, 8”, 6”,4”, 2”, 1” and 24”).Note: Tile sizes shown in Inches, not SquareInches (as used in custom tile size calculations).In other words, a 6” tile is really 6” x 6”, or a 36Square-Inch tile, but it is labeled as a 6” size.

s t - Stores Grout WidthStores Grout Width in Inches; used incalculating the number of tiles (seeabove). To recall this setting, pressr t. Default is 0 (no grout width).

Ç 2 - BrickCalculates the number of standard eight Inch-size U.S. bricks (with 3/8”mortar) based on entered linear distance (or area, volume) for both“face” (21-Square Inch) and “paver”(32-Square Inch) brick applications.


Ç 3 - BlockCalculates the number of standard128-Square Inch blocks (with 1/2”mortar), based on an entered lineardistance or area and a stored BlockArea (see below).

s 3 - Stores Block AreaStores Block Area in Square Inches.To recall this setting, press r 3.Default is 128 Square Inches(includes 1/2” mortar).Note: When calculating the number of blocks foran entered length, calculator uses a 16-Inch blocklength, as the majority of blocks are 16” long.

Ç 0 - GravelCalculates tons of gravel required, basedon an entered volume and a storedWeight per Volume (see below).

s 0 - Stores Gravel Weight per VolumeStores the number of Tons per CubicYard of gravel. To recall this setting,press r 0. Default is 1.5 tons perCubic Yard.
