Spike's Calculators

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

This calculator provides Imperial and Metric results.

- enter the circumference of the pipe in inches
- the length of the pipe in feet
- decimal precision, the number of digits after the decimal point

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

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