Spike's Calculators

Calculate a pipe's surface area using the diameter measurement in inches plus a fraction of an inch.

This calculator provides Imperial and Metric results.

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

- the circumference of the pipe in decimal inches
- the circumference inches
- the circumference in millimetres
- the surface area of the pipe in square inches
- the surface area in square feet
- 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 metre = 3.28083989501312 feet (ft) one cubic metre (m³) = 35.3146667214886 cubic feet (ft³)
