Pipe ID in inches, mm, or cm.
Quantity
Number of pipe runs.

Results

Volume
Total internal volume in cubic feet.
Gallons
Water capacity in US gallons.
Liters
Metric volume.
Water Weight
Weight if filled with water.

Example

100 ft of 4" PVC

4" inner diameter, 100 ft length, 1 pipe

radius = (4/12)/2 = 0.167 ftvolume = π × 0.167² × 100 = 8.7 cu ftgallons = 8.7 × 7.48 = 65.3 galwaterWeight = 65.3 × 8.34 = 544.5 lb

Common Use Cases

  • Plumbing system water capacity
  • Concrete filling of piles and caissons
  • Grout injection volume estimation
  • Fire suppression system sizing

Notes

  • Use inner diameter, not nominal pipe size (they differ).
  • Common 4" PVC has actual ID of 4.026".
