Factor1 L/hr = 0.004402868 gpm (US)

Converter

L/hr

Accepts numbers or expressions, e.g. 150 + 14.7

Result
4.40287gpm (US)

Rendered to 6 significant figures.

Formula

Formula
gpm (US) = L/hr × 0.004402868

Multiply any value in litres per hour by 0.004402868 to obtain the value in US gallons per minute.

Worked example

Convert 1000 L/hr to gpm (US).

  1. 01Start with 1000 L/hr.
  2. 02Multiply by the conversion factor: 1000 × 0.004402868 = 4.40287 gpm (US).
Result1000 L/hr = 4.40287 gpm (US)

FAQ

What is the conversion factor from L/hr to gpm (US)?
1 L/hr equals 0.004402868 gpm (US). To convert, multiply the value in litres per hour by 0.004402868.
How do I convert 1 L/hr to gpm (US)?
1 L/hr = 0.00440287 gpm (US). For any value, multiply by 0.004402868.
How do I convert gpm (US) back to L/hr?
Divide by the same factor — or equivalently, multiply by 227.1247. So 1 gpm (US) = 227.125 L/hr.
When would I need to convert litre per hour to US gallon per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. L/hr to gpm (US) is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
