Construction Calculator
Type 12' 6 1/2" + 3' 4 3/4" and get 15' 11 1/4": every length is added in inches and shown to 1/16 in, with decimal feet, meters and area or volume when you multiply.
Feet and Inches Calculator
Add measurements the way they read on the tape: 5' 10 1/2" + 3' 7 3/4" + 2' 1/8" is 11' 6 3/8", and 11' 6 3/8" is 3.51 m, or 351.5 cm.
Linear Feet Calculator
Linear feet = pieces x length: 12 boards at 8 ft plus 6 at 6 ft is 132 linear feet, or 19 eight-foot boards with 10% waste.
Linear Feet to Square Feet Calculator
Square feet = linear feet x board width in inches / 12: 100 linear feet of a 5 1/2 in wide board covers 45.83 sq ft.
Square Feet to Cubic Yards Calculator
Cubic yards = square feet x depth in inches / 12 / 27: 500 sq ft at 4 in deep is 6.17 cubic yards.
Cubic Yards to Tons Calculator (and Tons to Cubic Yards)
Tons = cubic yards x density in lb per cubic yard / 2,000: 10 cubic yards of dry gravel at 2,835 lb per yard is 14.2 tons.
