Calculate the area and perimeter of a diamond.
This calculator uses feet and or inches for measurements.
A diamond (rhombus) is a four-sided shape where all four sides are the same length, and the opposing angles are equal. If the angle is 90 degrees, it is a square.
The angle can not be more than 180°
A = s²sin(a) P = 4s where A is the area of the diamond s the length of a side the larger angle converted to radians P the perimeter of the diamond
one square foot ( ft²) = 144 square inches (in²) one square inch (in²) = 0.00694444444444443 square feet (ft²) one square foot ( ft²) = 0.09290304 square metres (m²) square inch (in²) = 0.00064516 square metres (m²)
