Formula

Formula
gal/day (US) = L/hr × 6.340129

Multiply any value in litres per hour by 6.340129 to obtain the value in US gallons per day.

Worked example

Convert 100 L/hr to gal/day (US).

  1. 01Start with 100 L/hr.
  2. 02Multiply by the conversion factor: 100 × 6.340129 = 634.013 gal/day (US).
Result100 L/hr = 634.013 gal/day (US)

FAQ

What is the conversion factor from L/hr to gal/day (US)?
1 L/hr equals 6.340129 gal/day (US). To convert, multiply the value in litres per hour by 6.340129.
How do I convert 1 L/hr to gal/day (US)?
1 L/hr = 6.34013 gal/day (US). For any value, multiply by 6.340129.
How do I convert gal/day (US) back to L/hr?
Divide by the same factor — or equivalently, multiply by 0.1577255. So 1 gal/day (US) = 0.157725 L/hr.
When would I need to convert litre per hour to US gallon per day?
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 gal/day (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).
