#### Calculator

1. enter the inside diameter of the pipe in millimetres
2. the outside diameter of the pipe in millimetres
3. the length of the pipe in metres
4. number of digits after the decimal point

#### Results

1. the pipe's wall thickness in millimetres
2. the wall thickness in inches
3. the inner circumference of the pipe in millimetres
4. the inner circumference of the pipe in inches
5. the inner surface area of the pipe in square centimetres
6. the inner surface area in square metres
7. the inner surface area in square inches
8. the inner surface area in square feet
9. the outer surface area of the pipe in square centimetres
10. the outer surface area in square metres
11. the outer surface area in square inches
12. the outer surface area in square feet

##### Circumference
`C = 2πR`
##### Surface Area
```S = D*π*L
where C is the circumference
π = 3.14159265
R the radius of the pipe
where S is the surface area in square units
D the pipe's diameter
L the length of the pipe
```
##### Conversions
```one inch (in) = 25.4 millimetres (mm)
one square inch (in²) = 0.00694444444444443 square feet (ft²)
one square inch (in²)= 6.4516 square centimetres (cm²)
one square inch (in²) = 0.00064516 square metres (m²)
