How to use

Enter numbers in the fields above; results update as you change inputs.

Formula

Core relationship: Time (min) = volume (gal) ÷ GPM

Idealized steady pump rate; hose lift and strainer clogging reduce real flow.

Practical use cases

Bilge Pump Time Calculator: passage planning, crew briefings, instrument-to-chart unit checks, and verifying mental math when tired or in rough weather.

Tips for accuracy

  • Match input units to your chart, GPS, or instrument before trusting the Bilge Pump Time Calculator.
  • Cross-check important outputs with a second method or crew when visibility or motion is poor.
  • Treat simplified models (waves, radar horizon, etc.) as estimates; real conditions vary.

Practical examples

  • 50 gal at 10 GPM → 5 min
