Abstract

The specification discloses a woodworking and home improvement calculator particularly adopted for symplifying common home improvement calculations. The calculator includes a variety of special keys including a gravel, cement, tile, brick, block, 4×8 sheet, paint, wallpaper, stud and roof bundle keys which allow the user to quickly determine the amount of materials needed for projects involving the aforementioned keys.

Claims

1. A calculator specially adapted to perform calculations and conversions of dimensional data for making home improvement calculations comprising in combination:

means responsive to a specific user key for calculating data related to one of gravel, concrete, tile, brick, block, 4×

8 sheet, paint, wallpaper, stud and roofing bundle calculations, and;

means for displaying said data related to one of gravel, concrete, tile, brick, block, 4×

8 sheet, paint, wallpaper, stud and roofing bundle calculations.

2. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a cubic dimension into a weight measurement based on a preset weight to volume ratio.

3. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a weight measurement into a dimensional measurement based on a preset weight to volume ratio.

4. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a cubic dimension into a weight measurement based on a user defined weight to volume ratio.

5. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a weight measurement into a cubic dimension based on a user defined weight to volume ratio.

6. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a cubic dimension into a weight measurement based on a weight to volume ratio chosen from a user selectable pre-set scrollable list.

7. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a weight measurement into a cubic dimension based on a weight to volume ratio chosen from a user selectable pre-set scrollable list.

8. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a cubic dimension into a weight measurement based on a weight to volume ratio chosen from a user selectable user set scrollable list.

9. The calculator of claim 1 wherein said means for determining data related to said gravel calculations allows for the conversion of a weight measurement into a cubic dimension based on a weight to volume ratio chosen from a user selectable pre-set scrollable list.

10. The calculator of claim 1 wherein said means for determining data related to said concrete calculations allows for the conversion of a cubic dimension into bags of cement based on either a pre-set or user defined weight to volume ratio.

11. The calculator of claim 1 wherein said means for determining data related to said concrete calculations allows for the conversion of bags of cement into a cubic dimension based on either a pre-set or user defined weight to volume ratio.

12. The calculator of claim 1 wherein said means for determining data related to said concrete calculations allows for the conversion of a cubic dimension into bags of cement, sand, aggregate and water based on either pre-set or user defined ratios.

13. The calculator of claim 1 wherein said means for determining data related to said tile calculations allows for the conversion of an area dimension into a number of tiles.

14. The calculator of claim 1 wherein said means for determining data related to said tile calculations allows for the conversion of a number of tiles into an area dimension.

15. The calculator of claim 1 wherein said means for determining data related to said tile calculations allows for the conversion of an area dimension into a number of tiles based on a scrollable list of tile sizes.

16. The calculator of claim 1 wherein said means for determining data related to said tile calculations allows for the conversion of a number of tiles into an area dimension based on a scrollable list of tile sizes.

17. The calculator of claim 1 wherein said means for determining data related to said brick calculations allows for the conversion of a number of bricks into an area dimension based on either the face or paver use of the brick.

18. The calculator of claim 1 wherein said means for determining data related to said brick calculations allows for the conversion of an area dimension into a number of bricks based on either the face or paver use of the brick.

19. The calculator of claim 1 wherein said means for determining data related to said brick calculations allows for the conversion of a linear dimension into a number of bricks based on either the face or paver use of the brick.

20. The calculator of claim 1 wherein said means for determining data related to said block calculations allows for the conversion of a number of blocks into an area dimension.

21. The calculator of claim 1 wherein said means for determining data related to said block calculations allows for the conversion of an area dimension into a number of blocks.
