# 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° `

#### Calculation

1. the length of a side in metres
2. one of the angles in degrees
3. decimal precision, the number of digits after the decimal point

#### Results

1. the second angle in degrees
2. the area of the diamond in square metres
3. the area in square feet
4. the area in square inches
5. the perimeter of the diamond in metres
6. the perimeter in feet
7. 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
```

##### Conversions
```one metre (m) = 3.28083989501312 feet (ft)
one metre (m) = 39.3700787401575 inches (in)
one square metre (m²) = 10.7639104167097 square feet (ft²)
one square metre (m²) = 1550.0031000062 square inches (in²)
