Calculate a result, save it as your baseline, then change the inputs to compare.
Rectangular Tank Volume
Internal length × width × height. Full geometric capacity.
Flow Converter
Volumetric flow. GPM always means US liquid gallons per minute.
Pressure Converter
Water-column units assume 1,000 kg/m³ density and standard gravity.
Pump Head / Pressure
Water only: density 1,000 kg/m³, gravity 9.80665 m/s². Not pump selection.
Pipe Volume
Cylinder volume using actual internal diameter, not nominal size.
Pipe Size Reference
Nominal inch labels and mathematical inch/mm values are different from physical pipe diameters.
Engineering Note: These tools are intended for quick reference and estimation. Verify final engineering selections, equipment sizing and code compliance according to project specifications and applicable UAE/international standards.
Unit factors follow NIST SI conversion references. Formulas & assumptions
