Electrical Wire Sizing Calculator vs Pipe Sizing Calculator

Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.

Engineering

Electrical Wire Sizing Calculator

Determines the minimum wire cross-sectional area needed to keep voltage drop within safe limits for a given load current and run length. Use it when wiring outlets, motors, or solar systems to avoid overheating and energy loss.

Answers
Minimum Wire Area Required (kcmil)
Inputs
Load Current, One-Way Distance, System Voltage, Maximum Voltage Drop, Conductor Material
Fluid Mechanics

Pipe Sizing Calculator

Find the minimum required pipe diameter to keep fluid velocity within safe limits for a given flow rate. Use this when selecting pipe sizes for new installations or checking whether existing pipes can handle increased flow.

Answers
Minimum Pipe Diameter (mm)
Inputs
Flow Rate, Maximum Velocity, Safety Factor
