- It's the most completed feet inch calculator plus common construction material calculation.
- Standard calculator look and feel to calculate Length, Area, and Volume by enter feet, inch and fraction.
- Input can be feet & inch (e.g. 2'6 1/2"), just inch (e.g. 5 3/4"), decimal feet (e.g 3.75 ft), or decimal inch (e.g 2.25") in the same calculation.
- Convert values between different units with the dimension.
- Convert feet and inches between decimal value and feet inch fraction format.
- Supported units: Feet, Inch, Yards, Meter, CM, MM, and Board Foot.
- It's easy to calculate lumber's linear board foot usage by enter the lumber's width, length, depth, and quantity, then convert to Board Foot unit.
- Function keys: Square, Square Root, Percent, sin, cos, tan, asin, acos, atan, Pythagorean Theorem and PI keys.
- Angle can be entered as Degree or Radian.
- With Percent key, it's easy to calculate the material waste.
- With Pythagorean Theorem key, just need two clicks to calculate hypotenuse of Right Triangle; no more need use with Square or Square Root keys.
- With the sin, cos, and tan keys, you can calculate distance with angle.
- Support M+ and M- memory keys to recall saved values.
- Calculate the Materials needed base on Length, Area, and Volume.
- User can customize the materials coverage to calculate the same category materials base on the needed.
- Supported material calculation: Concrete, Fence Post and boards, Gravel, Paint, Plywood, Roof Shingles, and Wall Studs.
- Built-in on-line user guide (Internet access required).
- Provide Haptic feedback (can turn off).
