Working Principle

This calculator converts flow rate from liters per hour to gallons per minute using a simple conversion factor. The conversion factor of 0.002228 is derived from the fact that:

  • 1 gallon ≈ 3.78541 liters
  • 1 hour = 60 minutes

Therefore, the conversion factor can be calculated as:

1 liter/hour = (1/3.78541) gallons/minute ≈ 0.264172 gallons/minute

However, for simplicity and practical use in many applications, the approximation 0.002228 (which is 1/448.8) is often used.
