Spike's Calculators

Calculate the inner and outer surface area of a pipe. With this calculator, you can calculate both surface areas of a pipe from the inside and outside diameter of the pipe using millimetres for pipe diameter and the length of the pipe in metres.

- enter the inside diameter of the pipe in millimetres
- the outside diameter of the pipe in millimetres
- the length of the pipe in metres
- number of digits after the decimal point

- the pipe's wall thickness in millimetres
- the wall thickness in inches
- the inner circumference of the pipe in millimetres
- the inner circumference of the pipe in inches
- the inner surface area of the pipe in square centimetres
- the inner surface area in square metres
- the inner surface area in square inches
- the inner surface area in square feet
- the outer surface area of the pipe in square centimetres
- the outer surface area in square metres
- the outer surface area in square inches
- the outer surface area in square feet

C = 2πR

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

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)
