Diamond (Rhombus)

Spike VM

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.

Formula
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

Conversions
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)
