Spike's Calculators

Calculate a pipe's surface area using the circumference measurement in millimetres.

This calculator provides Imperial and Metric results.

- enter the circumference of the pipe in millimetres
- the length of the pipe in metres
- decimal precision, the number of digits after the decimal point

- the diameter of the pipe in millimetres
- the diameter in inches
- the surface area of the pipe in square centimetres
- the surface area in square metres
- the surface area in square inches
- the surface area in square feet

S = C*L where S is the surface area in square units C the pipe's circumference L the length of the pipe
