Paint: Calculates volume of paint, based on
an entered area and a stored Paint Coverage
per Gallon. Finds quantity in Gallons, Quarts
or Pints upon repeated presses.
Paint Coverage: Stores Paint Coverage
per Gallon in Square Feet. To recall
this setting, press . Default
is 350 Square Feet per Gallon.
Tile: Finds the number of tiles, based on
an entered area and a user-stored Grout
Width. Repeated presses will scroll between
numbers of tiles for various “standard” tile
sizes (24", 18", 16", 13", 12", 10", 8", 6", 4", 2",
and 1").
Note: Tile sizes shown in Inches, not Square Inches.
In other words, a 6 Inch tile is really 6 Inches x 6
Inches, or a 36 Square Inch tile, but it is labeled as a
6 Inch-size.
Grout Width: Stores Grout Width
in Inches; used in calculating the
number of tiles. To recall this setting,
press . Default is 0 (no
grout width).

Note: Automatically adds one stud to the calculated
answer to account for one on the end.
On-center for Studs: Stores On-center
spacing for studs in Inches. To recall
this setting, press .
Default is 16 Inches.
Flooring: Calculates the required length
for 12', 13', 15' or 6' wide rolls, based on an
entered area. Calculates the coverage area,

sheets, based on entered linear
distance or area.
Custom Tile: Calculates number of tiles
needed based on an entered area and a
stored Tile Size. This is used separately from
the regular Tile Key ( ).
Note: Calculation does not account for grout width
for custom tiles, so you will need to adjust for this.
