  1. enter the circumference of the pipe in inches
  2. the length of the pipe in feet
  3. decimal precision, the number of digits after the decimal point


  1. the diameter in inches
  2. the diameter in millimetres
  3. the surface area of the pipe in square inches
  4. the surface area in square feet
  5. the surface area in square square centimetres
  6. the surface area in square metres

Surface Area
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)
