Water Calculators
Estimate water volume for pools, ponds, tanks, and pipes, then convert GPM or LPM flow rates for bucket-fill measurements and common water-system units.
Pool Volume Calculator
Estimate pool gallons or liters from shape, dimensions, and shallow/deep depths.
Pond Volume Calculator
Estimate pond gallons or liters for backyard water gardens, koi ponds, and farm ponds.
Tank Volume Calculator
Estimate tank gallons or liters for cylinders, rectangular tanks, and capsule shapes.
Pipe Volume Calculator
Estimate gallons or liters held in a pipe from actual inner diameter and length.
Gallons Per Minute Calculator
Find GPM from a bucket fill or convert another flow rate into gallons per minute.
Liters Per Minute Calculator
Convert LPM to common flow units or measure liters per minute from a bucket fill.
