Diamond (Rhombus) - Metric
Calculate the area and perimeter of a diamond.
This calculator uses metres 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.
Note:
The angle can not be more than 180°
Diamond Area and Perimeter - Metric
Calculation
- the length of a side in metres
- one of the angles in degrees
- decimal precision, the number of digits after the decimal point
Results
- the second angle in degrees
- the area of the diamond in square metres
- the area in square feet
- the area in square inches
- the perimeter of the diamond in metres
- the perimeter in feet
- the perimeter in inches
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
